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.
