This change worked to build test and run a version of GMP-6.2.0 for my PC.
The PC is running Msys2 under Windows 10 and without change GMP failed
to build.
The following change and:
autoconf
./configure
make
make check
make install
built a working static version of GMP for my x86_64 Skylake PC.
With very limited understanding of the Gnu-tools I was unable to make a
shared (.dll) version although Msys2 provides a generic one.

Thanks for the great GMP support.
