  Compile results in the following. According to Stallman I believe you
  are supposed to add the necessary options to compile the file
  independent of CFLAGS, and it should not need to be override-able by
  the user because it is required. Also see
  https://www.gnu.org/prep/standards/html_node/Command-Variables.html .

Are you implicitly saying that you're overriding CFLAGS (at "make" time)
and then things fail and that it shouldn't fail?

If I guess right, my recommendation is that you don't override CFLAGS in
a build-breaking manner.

If I guess wrong, please spell our what you do and what you think is
wrong in GMP.
