You mean, _CL_CONFIG_PUBLIC_H is defined elsewhere? I think you are
experiencing interferences with another installation of CLN.

Can you, please, have a look at the test program emitted by m4/gmp.m4
and see why it gets this wrong?

Okay. I think it's best to fix top issues first.

I'm taking this to the mailing list cln-list at ginac.de. Please subscribe
to it. I'm afraid, I cannot help you any better since I don't know
anything about cygwin-64. But maybe someone on that list can offer some
advice.

Best wishes
    -rbk.
