 Log Message:
 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.
 - 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).
 - 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).
 * programs linked with camlp4lib.cma now also need dynlink.cma.
