Ended up defining NO_DSHOW_STRSAFE in mf_utils.h,
just like dshow_capture.h does (these are the only two uses).

-D_CRT_SECURE_NO_WARNINGS -D_CRT_NONSTDC_NO_WARNINGS
are defined only for MVSC:

elif test_${pfx}cpp_condition crtversion.h "defined _VC_CRT_MAJOR_VERSION"; then

NO_DSHOW_STRSAFE should cover MinGW as well, and probably others.
If you still want global NO_DSHOW_STRSAFE, please point where to add it exactly.
