dyn_load.c: Renamed GC_win32s to GC_no_win32_dlls.
2002-03-12 Adam Megacz <adam@xwt.org>
* dyn_load.c: Renamed GC_win32s to GC_no_win32_dlls.
* misc.c: Renamed GC_is_win32s() to GC_no_win32_dlls
* os_dep.c: Renamed GC_win32s to GC_no_win32_dlls and
statically initialized it to TRUE if compiling with GCC.
* win32_threads.c (thread_start): We no longer use SEH if
compiling with GCC.
* mark.c (GC_mark_some): We no longer use SEH if
compiling with GCC.
