Are you using mingw32 or mingw-w64? It works for me with mingw-w64, and 
mingw32's headers are known for missing things, so if you're using 
mingw32 it could be missing the timespec struct.

I can change the check in threads.h to _TIMESPEC_DEFINED, which is what 
my mingw-w64 headers define when declaring the timespec struct, though I 
don't know if other Windows compilers that have timespec will also set that.
