Building **version 1.0.2** for mingw32 without pthreads support fails:

Fix is to declare "_global_image_glyph_cache_mutex" in "cairo-win32-surface.c"
and to initialize it in "DllMain".

Wondering why that mutex doesn't has a "cairo" prefix like its friends.

Created attachment 3477 [details] [review]
A fix for the problem.

Comment 2 Carl Worth 2005-10-04 12:26:15 UTC

Thanks for the report. This fix has already been applied to 1.0.3.

(And, FYI, in 1.1.1 where the original DllMain originated, the mutex objects all
have consistent names.)
