gcc-9 is old. Isn't mingw.org abandoned? I thought everyone had moved to
mingw-w64.org.
using ABI="64"

CFLAGS="-Wno-attribute"
Specifying CFLAGS yourself is not a great idea, it prevents GMP from
adding nice optimization flags. If you really want to pass -Wno-attribute,
either put it in CPPFLAGS, or run configure once without CFLAGS to see
what GMP wants to use, and add -Wno-attribute to that.
This error seems to be related to changing the ABI after the initial
configure. Using "make distclean" fixes this.
I therefore think that something like `AC_ARG_VAR([ABI], [Application Binary
Interface to use])` (maybe also reference
https://gmplib.org/manual/ABI-and-ISA in its description) should be added to
configure.ac to make that error on an ABI change and also adding this missing
piece to configure's help output.
You mean this?
https://gmplib.org/repo/gmp-6.3/file/tip/configure.ac#l455
I think it has been there for a while.
