I'm not sure I understand what happens.

Can you explain how the M4 variable in GMPs configure script propagates
to the configuration of gcc? As a shell variable (I don't even know if
configure variables like this are supposed to be exported), or via
substitution in some Makefile, or via config.cache, or...

I understand neither the reason for the current behaviour, nor the
details of the problem it causes.
