core missing __MINGW32__ directive in time_render.c & vec.c

[WallyZambotti]

In time_render.c the following line 18-20:

AG_Cond agCondBeginRender;
AG_Cond agCondEndRender;
AG_Mutex agCondRenderLock;

Should be changed for:

#ifdef __MINGW32__
__declspec(dllexport) AG_Cond agCondBeginRender;
__declspec(dllexport) AG_Cond agCondEndRender;
__declspec(dllexport) AG_Mutex agCondRenderLock;
#else
AG_Cond agCondBeginRender;
AG_Cond agCondEndRender;
AG_Mutex agCondRenderLock;
#endif

In vec.c the following lines 35-36:

int
ag_vec_expand_(char **data, int *length, int *capacity, int memsz)

should be replaced with:

int
#ifdef __MINGW32__
__declspec(dllexport) ag_vec_expand_(char **data, int *length, int *capacity, int memsz)
#else
ag_vec_expand_(char **data, int *length, int *capacity, int memsz)
#endif

Without these directives compilation will fail if using libtool under CygWin/Msys64 Mingw64

Is this still an issue? I can't seem to be able to reproduce the problem with msys2.
