Multiple GMP builds - "make" options?

[White, Jim (ITD)]

I'm using MinGW on a PC to build GMP shared libraries.

I build one version (e.g. for cpu type "pentium4") with
no problems.

Then I try to rebuild another version (e.g. for cpu type "athlon"),
so I rerun "configure" with the new cpu type.

But when I execute the "make" command nothing gets recompiled! 
It just produces a series of messages of the form 
"Nothing to do in ...".

How can I specify that I really do want everything 
recompiled/rebuilt??


Cheers
