2008-07-25  Hans Boehm <Hans.Boehm@hp.com> (Really mostly Ivan Maidanski)
Ivan's description of the patch follows. Note that a few pieces like
the GC_malloc(0) patch, were not applied since an alternate had been
previously applied.  A few differed stylistically from the rest of
the code (mostly casts to void * instead of target type),
or were classified as too minor to bother.  Note that
all of Ivan's static declarations which did not correct outright
naming bugs (as a few did), where replaced by STATIC, which is
ignored by default.

        - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
  GC_malloc(0));
        - addition of missing getter/setter functions for public variables
  (may be useful if compiled as Win32 DLL);
        - addition of missing GC_API for some exported functions;
        - addition of missing "static" declarator for internal functions
   and variables (where possible);
        - replacement of all remaining K&R-style definitions with ANSI
  C ones (__STDC__ macro is not used anymore);
        - addition of some Win32 macro definitions (that may be missing in
  the standard headers supplied with a compiler) for GWW_VDB mode;
        - elimination of most compiler warnings (except for
  "uninitialized data" warning);
        - several typos correction;
        - missing parenthesis addition in macros in some header files of
  "libatomic_ops" module.

My highlights based on reading the patch:

* allchblk.c: Remove GC_freehblk_ptr decl.
