There was a problem hiding this comment.
I believe this needs to be BOOl WINAPI so that it gets defined with the __stdcall calling convention rather than __cdecl
Otherwise:
error C2440: 'function': cannot convert from 'BOOL (__cdecl *)(PINIT_ONCE,PVOID,PVOID *)' to 'PINIT_ONCE_FN'
warning C4024: 'InitOnceExecuteOnce': different types for formal and actual parameter 2

DllMain wouldn't be called if the library is statically linked, so this instead initializes it in epoxy_handle_external_wglMakeCurrent instead of DllMain if it hasn't yet been initialized. By using INIT_ONCE, this is threadsafe.
Cf. #200
