diff th_types.h @ 746:a557d1b2a356
Move TH_ATTR_PRINTF_FMT macro definition to th_types.h and improve the
preprocessor checks. Apparently newer versions (not sure since which
version exactly) seem to work fine with the attribute defined.
Enabling for MinGW GCC >= 12 for now, though it may have worked earlier.
