The failures I had on some GMP DLLS manifested with both gcc and tcc 
compilers.

In any case, the GMP DLL will have its own set of dynamic imports 
(static imports will be part of its code). The failing one imported 
these dynamic libraries:

     Name:             VCRUNTIME140.dll
     Name:             api-ms-win-crt-runtime-l1-1-0.dll
     Name:             api-ms-win-crt-stdio-l1-1-0.dll
     Name:             api-ms-win-crt-string-l1-1-0.dll
     Name:             api-ms-win-crt-locale-l1-1-0.dll
     Name:             api-ms-win-crt-heap-l1-1-0.dll
     Name:             api-ms-win-crt-convert-l1-1-0.dll
     Name:             KERNEL32.dll

And the working one (gcc/tcc) imported these:

     Name:             KERNEL32.dll
     Name:             api-ms-win-crt-convert-l1-1-0.dll
     Name:             api-ms-win-crt-environment-l1-1-0.dll
     Name:             api-ms-win-crt-filesystem-l1-1-0.dll
     Name:             api-ms-win-crt-heap-l1-1-0.dll
     Name:             api-ms-win-crt-locale-l1-1-0.dll
     Name:             api-ms-win-crt-private-l1-1-0.dll
     Name:             api-ms-win-crt-runtime-l1-1-0.dll
     Name:             api-ms-win-crt-stdio-l1-1-0.dll
     Name:             api-ms-win-crt-string-l1-1-0.dll
     Name:             api-ms-win-crt-time-l1-1-0.dll
     Name:             api-ms-win-crt-utility-l1-1-0.dll

So nothing to do with tcc.
