Yes, I know. I would like to try to use the gmp.h header without
changes, if possible, since that makes it easier for others to build
Emacs.

You mean, on the bignum branch or on master/emacs-26? If the latter,
is the dependency on libgmp recorded in the binary, or do you see it
in a running session? In either case, is the dependency direct in
Emacs or indirect via some other library, and if so, which library
causes the dependency?

That's what I don't understand, yet.
