update thread's last_stack_min value (only if GC_dont_query_stack_min). * win32_threads.c (GC_push_stack_for): Skip assertion for WinCE if GC_dont_query_stack_min (since the evaluated stack_min value

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. Make free_list_index_of() static. * include/gc.h: Use __int64 on win64, define GC_oom_func, GC_finalizer_notifier_proc, GC_finalizer_notifier_proc, add getter and setters: GC_get_gc_no, GC_get_parallel, GC_set_oom_fn, GC_set_finalize_on_demand, GC_set_java_finalization, GC_set_dont_expand, GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect, GC_set_finalizer_notifier.
