annotate src/thread/win32/SDL_systhread.c @ 1242:caf0328c8058
Add XME hooks to X11 driver instead of relying on libxme...libxme hasn't
changed in five years, and it's a small .c file that just calls into the X11
dependencies we already use elsewhere. Including it directly allows us to
make use of the dynamic X11 code.
Fixes Bugzilla #41.
