This is irksome. :-) Is it safe to assume that you ran "make clean"
and that the intdiv extension is compiled with the same version of
MPFR as gawk is? Not that this should be an actual problem, since the
library should be checking the versions at runtime. Hmmm...

But to be safe: was the intdiv extension also built with MPFR 3.1.6?
I don't see this problem on Fedora 27 with MPFR 3.1.5. I'm building
3.1.6 now...
