* gdk/gdkrgb.c: actually builds and runs properly on big endian machines now, because we #include config.h. Also fixed up a compile error in the WORDS_BIGENDIAN case in gdk_rgb_convert_565_gray. I made the fix by looking at patterns in the other code; Raph can you verify this? * gdk/gdkthreads.c: #include <unistd.h> to quell compiler warnings -Yosh
