The c99 compiler is pretty compliant, if I a bit strict.
The sed issue is pretty common on the platform but does not seem to block any other Open Source configure script. It looks like a ^M issue but I can't figure out how or why yet. We're on GNU sed 4.2.2, which I admit is 8 years old - outside of my control.

The issue seems to be in stdio.h, which exists. I think the critical missing line is as follows in gmp-h.in, which needs to be added.

  || defined (_STDIO)                 /* HPE NonStop */         \

With that change, compiles succeed, with a few warnings about the _dummy variable. make check all passes. I think we could consider GMP "ported" now.

Thanks,
