Update to O'Caml 3.12.1


Changes in Objective Caml 3.12.1:

Features:
- added '-ml-synonym' and '-mli-synonym' options to ocamldep
- added '-ocamldoc' option to ocamlbuild
- added possibility to add options to ocamlbuild
- added access to current camlp4 parsers and printers
- improved instruction selection for float operations on amd64
- stdlib: added a 'usage_string' function to Arg
- allow with constraints to add a type equation to a datatype definition
- ocamldoc: allow to merge '@before' tags like other ones
- ocamlbuild: allow dependency on file "_oasis"

Other changes:
- Changed default minor heap size from 32k to 256k words.
- Added new operation 'compare_ext' to custom blocks, called when
  comparing a custom block value with an unboxed integer.

Multiple bug fixes.

PKGREVISION must not be in Makefile.common.

move PKGREVISION to each Makefile including the Makefile.common for
keep version number, and bump again for ocaml-graphics because the
previous bump resuited in downgrade.

Enable native dynamic loading support on NetBSD/{i386,amd64}.

Bump pkgrevision.

While I'm here: add a comment to patch-at explaining what it does.

Tested by

$ make install
$ cd work/ocaml-3.12.0/testsuite && gmake one DIR=tests/lib-dynlink-native

(Not in a build-env because that uses the wrappers, which don't let the
test suite see the installed OCaml files.)

This is only a workaround on NetBSD/{i386,amd64} for the problems of
OCaml PR#5049 <http://caml.inria.fr/mantis/view.php?id=5049>.  (E.g.,
this workaround makes Coccinelle build on those platforms -- but it
still won't build on platforms with native compilation but no native
dynamic loading.  Need to hack everything that uses dynlink to have
four compile-time cases -- {yes,no} {byte,nat}dynlink.)

Pass CFLAGS and LDFLAGS to the compiler (fixes problems e.g. on Mac OS X); pkglint clean-up

- Enable native compilation for arm.

- to do this, and make the result runnable on pre-thumb arm, change
  upstreams assembler snippets and stubs to use "mov pc,reg" instead
  of the return/call-to-thumb-friendly "bx reg", which is not available
  in non-thumb-enabled arm CPUs. Whether this is the way to go, or a
  seperate "armt" architecture for ocaml is needed, needs to be discussed
  with upstream.

Resulting compiler, when running its selftest suite, has 6 errors less than
the same on i386. Unison compiled natively with this passes its self-test.

Log Message:
Make this package work again on architectures where we don't compile
natively (that is, only to byte-code).

This consists of two parts:

a) a patch to ocamldoc/Makefile to make it create the man pages using
the interpreted ocamldoc - this exists for both types of architectures,
so is safe. (This will be sent up-stream).

b) move a common shared library file to the common PLIST, and a lot of
files (natively compiled versions of the ML modules and natively compiled
versions of a few binaries) to PLIST.opt.

This has been build-tested on i386 (cross-compiled from amd64) and on
arm. unison builds and works.

"make test" shows the same amount of passed and failed tests (mostly
non-found libraries) as before; but this needs more investigation.

An additional issue to solve (with upstream) is that there's no easy way
to run the part of the test suite that would work on byte-code-only
architectures.

Update to O'Caml 3.12.0, add test target.

Some of the highlights in release 3.12 are:

  * Polymorphic recursion is supported, using explicit type
    declarations on the recursively-defined identifiers.
  * First-class modules: module expressions can be embedded as
    values of the core language, then manipulated like any other
    first-class value, then projected back to the module level.
  * New operator to modify a signature a posteriori: S with type
    t := tau denotes signature S where the t type component is
    removed and substituted by the type tau elsewhere.
  * New notations for record expressions and record patterns:
    { lbl } as shorthand for { lbl = lbl }, and { ...; _ } marks
    record patterns where some labels were intentionally omitted.
  * Local open let open ... in ... now supported by popular demand.
  * Type variables can be bound as type parameters to functions;
    such types are treated like abstract types within the
    function body, and like type variables (possibly generalized)
    outside.
  * The module type of construct enables to recover the module
    type of a given module.
  * Explicit method override using the method! keyword, with
    associated warnings and errors.

Fix x11/labltk for ocaml 3.11.1 [PR pkg/42017]

Update lang/ocaml to 3.11.1 [PR pkg/41695]

(Changes that can break existing programs are marked with a "*"  )
Language features:
- Addition of lazy patterns: "lazy <pat>" matches suspensions whose values,
  after forcing, match the pattern <pat>.
- Introduction of private abbreviation types "type t = private <type-expr>",
  for abstracting the actual manifest type in type abbreviations.
- Subtyping is now allowed between a private abbreviation and its definition,
  and between a polymorphic method and its monomorphic instance.

Compilers:
- The file name for a compilation unit should correspond to a valid
  identifier (Otherwise dynamic linking and other things can fail, and
  a warning is emitted.)
* Revised -output-obj: the output name must now be provided; its
  extension must be one of .o/.obj, .so/.dll, or .c for the
  bytecode compiler. The compilers can now produce a shared library
  (with all the needed -ccopts/-ccobjs options) directly.
- -dtypes renamed to -annot, records (in .annot files) which function calls
  are tail calls.
- All compiler error messages now include a file name and location, for
  better interaction with Emacs' compilation mode.
- Optimized compilation of "lazy e" when the argument "e" is
  already evaluated.
- Optimized compilation of equality tests with a variant constant constructor.
- The -dllib options recorded in libraries are no longer ignored when
  -use_runtime or -use_prims is used (unless -no_auto_link is
  explicitly used).
- Check that at most one of -pack, -a, -shared, -c, -output-obj is
  given on the command line.
- Optimized compilation of private types as regular manifest types
  (e.g. abbreviation to float, float array or record types with only
   float fields).

Native-code compiler:
- New port: Mac OS X / Intel in 64-bit mode (configure with -cc "gcc -m64").
- A new option "-shared" to produce a plugin that can be dynamically
  loaded with the native version of Dynlink.
- A new option "-nodynlink" to enable optimizations valid only for code
  that is never dynlinked (no-op except for AMD64).
- More aggressive unboxing of floats and boxed integers.
- Can select which assembler and asm options to use at configuration time.

Run-time system:
- New implementation of the page table describing the heap (two-level
  array in 32 bits, sparse hashtable in 64 bits), fixes issues with address
  space randomization on 64-bit OS (PR#4448).
- New "generational" API for registering global memory roots with the GC,
  enables faster scanning of global roots.
  (The functions are caml_*_generational_global_root in <caml/memory.h>.)
- New function "caml_raise_with_args" to raise an exception with several
  arguments from C.
- Changes in implementation of dynamic linking of C code:
  under Win32, use Alain Frisch's flexdll implementation of the dlopen
  API; under MacOSX, use dlopen API instead of MacOSX bundle API.
- Programs may now choose a first-fit allocation policy instead of
  the default next-fit.  First-fit reduces fragmentation but is
  slightly slower in some cases.

Standard library:
- Parsing library: new function "set_trace" to programmatically turn
  on or off the printing of a trace during parsing.
- Printexc library: new functions "print_backtrace" and "get_backtrace"
  to obtain a stack backtrace of the most recently raised exception.
  New function "record_backtrace" to turn the exception backtrace mechanism
  on or off from within a program.
- Scanf library: fine-tuning of meta format implementation;
  fscanf behaviour revisited: only one input buffer is allocated for any
  given input channel;
  the %n conversion does not count a lookahead character as read.

Other libraries:
- Dynlink: on some platforms, the Dynlink library is now available in
  native code. The boolean Dynlink.is_native allows the program to
  know whether it has been compiled in bytecode or in native code.
- Bigarrays: added "unsafe_get" and "unsafe_set"
  (non-bound-checking versions of "get" and "set").
- Bigarrays: removed limitation "array dimension < 2^31".
- Labltk: added support for TK 8.5.
- Num: added conversions between big_int and int32, nativeint, int64.
  More efficient implementation of Num.quo_num and Num.mod_num.
- Threads: improved efficiency of mutex and condition variable operations;
  improved interaction with Unix.fork (PR#4577).
- Unix: added getsockopt_error returning type Unix.error.
  Added support for TCP_NODELAY and IPV6_ONLY socket options.
- Win32 Unix: "select" now supports all kinds of file descriptors.
  Improved emulation of "lockf" (PR#4609).

Tools:
- ocamldebug now supported under Windows (MSVC and Mingw ports),
  but without the replay feature.  (Contributed by Dmitry Bely
  and Sylvain Le Gall at OCamlCore with support from Lexifi.)
- ocamldoc: new option -no-module-constraint-filter to include functions
  hidden by signature constraint in documentation.
- ocamlmklib and ocamldep.opt now available under Windows ports.
- ocamlmklib no longer supports the -implib option.
- ocamlnat: an experimental native toplevel (not built by default).

Camlp4:
* programs linked with camlp4lib.cma now also need dynlink.cma.

Fix PLIST of ocaml-graphics for architectures not using the optimiser.
Add amd64 to that list. Bump revision of ocaml-graphics. Make ocaml
itself and ocaml-graphics destdir safe.

- ocamldoc: new option -short-functors to use a short form to display
    functors in html generator
- ocamlprof: added "-version" option

Update lang/ocaml to 3.09.2.

Changes from 3.09.1:
----
Bug fixes:
- Makefile: problem with "make world.opt"
- compilers: problem compiling several modules with one command line
- compilers,ocamldoc: error message that Emacs cannot parse
- compilers: crash when printing type error
- compilers: -dtypes wrong for monomorphic type variables
- compilers: wrong warning on optional arguments
- compilers: crash when wrong use of type constructor in let rec
- compilers: better wording of "statement never returns" warning
- runtime: inefficiency of signal handling
- runtime: crashes with I/O in multithread programs
- camlp4: empty file name in error messages
- camlp4: stack overflow
- otherlibs/labltk: ocamlbrowser ignores its command line options
- otherlibs/unix: Unix.times wrong under Mac OS X
- otherlibs/unix: wrong doc for execvp and execvpe
- otherlibs/win32unix: random crash in Unix.stat
- stdlib: update_mod not found under Windows
- stdlib: Filename.dirname/basename wrong on Win32
- stdlib: incomplete documentation of Pervasives.abs
- stdlib: Printf bugs
- tools/checkstack.c missing include
- yacc: crash when given argument "-"

New features:
- ported to MacOS X on Intel
- configure: added support for GNU Hurd

Added support for dynamic loading on NetBSD. Bumped PKGREVISION.
Fixed almost all pkglint -Wall warnings.

Changes 3.09.1:

* Bug fixes
* New features:
- otherlibs/labltk: browser uses menu bars instead of menu buttons


Changes 3.09.0:

Language features:
- Introduction of private row types, for abstracting the row in object
  and variant types.

Type checking:
- Polymorphic variants with at most one constructor [< `A of t] are no
  longer systematically promoted to the exact type [`A of t]. This was
  more confusing than useful, and created problems with private row
  types.

Native-code compiler (ocamlopt):
* Revised implementation of the -pack option (packing of several compilation
  units into one).  The .cmx files that are to be packed with
  "ocamlopt -pack -o P.cmx" must be compiled with "ocamlopt -for-pack P".
  In exchange for this additional constraint, ocamlopt -pack is now
  available on all platforms (no need for binutils).
* Fixed wrong evaluation order for arguments to certain inlined functions.

* Other (see 'Changes')

Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in

    http://mail-index.netbsd.org/tech-pkg/2005/12/02/0034.html

Updating lang/ocaml to 3.08.4 (PR 31128)

This is mainly a bug fix release, fixing code generation under amd64 and some
OO compilation problems, among many others

approved by adam@

Let x11/labltk use bdb if native ndbm is not available.

Remove USE_GNU_TOOLS and replace with the correct USE_TOOLS definitions:

	USE_GNU_TOOLS	-> USE_TOOLS
	awk		-> gawk
	m4		-> gm4
	make		-> gmake
	sed		-> gsed
	yacc		-> bison

Do not strip commands on Linux, where some of them are not regular binaries.

Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

New maintainer, new distfile

Changes 3.08.3:
New features:
- support for ocamlopt -pack under Mac OS X (PR#2634, PR#3320)
- ignore unknown warning options for forward and backward compatibility
- runtime: export caml_compare_unordered (PR#3479)
- camlp4: install argl.* files (PR#3439)
- ocamldoc: add -man-section option
- labltk: add the "solid" relief option (PR#3343)
- compiler: ocamlc -i now prints variance annotations

Bug fixes:
- typing: fix unsoundness in type declaration variance inference.
    Type parameters which are constrained must now have an explicit variant
    annotation, otherwise they are invariant. This is not backward
    compatible, so this might break code which either uses subtyping or
    uses the relaxed value restriction (i.e. was not typable before 3.07)
- typing: erroneous partial match warning for polymorphic variants (PR#3424)
- runtime: handle the case of an empty command line (PR#3409, PR#3444)
- stdlib: make Sys.executable_name an absolute path in native code (PR#3303)
- runtime: fix memory leak in finalise.c
- runtime: auto-trigger compaction even if gc is called manually (PR#3392)
- stdlib: fix segfault in Obj.dup on zero-sized values (PR#3406)
- camlp4: correct parsing of the $ identifier (PR#3310, PR#3469)
- windows (MS tools): use link /lib instead of lib (PR#3333)
- windows (MS tools): change default install destination
- autoconf: better checking of SSE2 instructions (PR#3329, PR#3330)
- graphics: make close_graph close the X display as well as the window (PR#3312)
- num: fix big_int_of_string (empty string) (PR#3483)
- num: fix big bug on 64-bit architecture (PR#3299)
- str: better documentation of string_match and string_partial_match (PR#3395)
- unix: fix file descriptor leak in Unix.accept (PR#3423)
- unix: miscellaneous clean-ups
- unix: fix documentation of Unix.tm (PR#3341)
- graphics: fix problem when allocating lots of images under Windows (PR#3433)
- compiler: fix error message with -pack when .cmi is missing (PR#3028)
- cygwin: fix problem with compilation of camlheader (PR#3485)
- stdlib: Filename.basename doesn't return an empty string any more (PR#3451)
- stdlib: better documentation of Open_excl flag (PR#3450)
- ocamlcp: accept -thread option (PR#3511)
- ocamldep: handle spaces in file names (PR#3370)
- compiler: remove spurious warning in pattern-matching on variants (PR#3424)
- windows: better handling of InterpreterPath registry entry (PR#3334, PR#3432)

With mk/ fix for PR pkg/29031, the _STRIPFLAG_* hack is no longer needed.

- Update from 3.06 to 3.08.2
- Lots of changes/bugfixes - see Changes for all the details

Override config.guess and config.sub manually, since GNU_CONFIGURE is not
correct here (and thus automatic overriding doesn't work).

Do not depend on Tk nor X11.  Two new packages will be added to provide
the missing bits, namely labltk and ocaml-graphics, respectively.  To
simplify this, add a Makefile.common.  Bump PKGREVISION to 8.

Per discussion with wiz@ a while ago.
