* alloc.c (GC_gcollect): Pass 0 as stop_func instead of
GC_default_stop_func (to prevent data races).

NetBSD platform detection code (check that other GC_xxx_THREADS
are undefined); add FIXME.

2009-10-06  Ivan Maidanski <ivmai@mail.ru>

* include/gc_config_macros.h: Rearrange the platform detection
code (GC_WIN32_PTHREADS implies GC_WIN32_THREADS; define
GC_THREADS first if GC_XXX_THREADS already set; define proper
GC_XXX_THREADS if GC_THREADS; define GC_PTHREADS in a single
place; define _REENTRANT if posix threads except for Win32).
* include/gc_config_macros.h: Reformat the code (make the
indentation style uniform across the file).

2009-10-06  Ivan Maidanski <ivmai@mail.ru>

* tests/test.c (window_proc): Call GC_gcollect_and_unmap() on
WM_HIBERNATE event (instead of GC_set_force_unmap_on_gcollect()
and GC_gcollect()).

2009-10-06  Ivan Maidanski <ivmai@mail.ru>

* include/gc.h (GC_allow_register_threads, GC_register_my_thread,
GC_unregister_my_thread, GC_malloc_many): Refine the comment.
* include/gc.h (GC_malloc_many, GC_NEXT): Declare unconditionally
(that is, don't depend on GC_THREADS macro).
* include/gc.h: Don't check for __CYGWIN32__ and __CYGWIN__ along
with a check for GC_PTHREADS (since the former implies the
latter).

2009-10-06  Ivan Maidanski <ivmai@mail.ru>

* include/gc.h: Reformat the code (make the indentation style
uniform across the file).
