No. Me overriding your flags is:

    ./configure ....
    make CFLAGS="..."

In this case I stomp on your flags.

No, we cannot work from there. GMP selects screwed up release flags.
They are dangerous and insecure.

GMP is the only project I know that cannot handle simple release build
flags. And I build 66 of them here:
https://github.com/noloader/Build-Scripts .

GMP really should follow GNU Coding Standards. It is not that hard.
