OK, tell me where to get ready-made DLLs for GMP and LIBFFI that I can can use on Windows. If that's not possible then there is no choice (other than not to use them at all, which is what I do).

 So do you think that those projects are /forcing/ you to use their code?   Are the folks who wrote GMP responsible for /your/ insistence on using /their/ code, without using additional tools or libraries?  You want to use what probably amounts to hundreds of person-years of specialised work, for free, and you are not willing to go to the effort of downloading and installing a few other bits of /free/ software first, in order to be able to follow freely available instructions found online?
 And you blame the GMP and LIBFFI for all this?  They are, after all, holding a gun to your head and insisting that you use their software while viscously and maliciously refusing to re-write their code to remove traces of code that rely on the platforms they use themselves.
 Or maybe it is now /my/ responsibility to find these dll's for you?
 Well, you are in luck :
 <https://packages.msys2.org/packages/mingw-w64-ucrt-x86_64-gmp>
<https://packages.msys2.org/packages/mingw-w64-ucrt-x86_64-libffi>
 The compressed tarballs include the dlls.

I downloaded a couple of large files, including mingw64-x86_64-gmp-6.3.0-1-src.tar, but found no trace of any DLL files.
(But I'm pleased that the GMP configure script hasn't grown beyond 30583 lines. When they manage 0 lines, let me know.)
Meanwhile here is the library *I* had to use instead:
   https://github.com/sal55/langs/tree/master/bignum
There are 4 files:
   bignum.c         Source code
   bignum.h         Header provides the API
   bignum.dll       Prebuilt binary
   pid.c            Demo to show it works
You can build bignum.c into the .dll yourself (sorry, I don't have a 40,000-line configure script or massive makefile for that, you'll have to figure it out yourself!), or compile it into your application.
The demo (shows digits of pi) is built like this:
   tcc pid.c bignum.dll
This is what simplicity looks like.
(GMP now includes 'minigmp', which is one-file version plus headers. Performance is roughly on a par with my library.
However my library uses decimal representation, and includes arbitrary precision floating point.)
Oh, and it's open source and is in public domain.
