It sounds like you ended up with gcc distro based on 12 y.o. Microsoft
DLL that does not support majority of c11 library features and likely
does not support few c99 library features as well.
If you were a little less stubborn, in 10 minutes you could have have
distro based on new ucrt DLL that is closer to new C standard and
generates smaller binaries.
And likely occupies less than 1.4 GB.

BTW, I don't understand why MSVC produces smaller binaries with old MS C
RTL DLL while gcc produces smaller binaries with new MS C RTL DLL.
But that's undeniable fact.
