Thanks for your reply Peter.
The path in the shell is already set to the required compiler. I need to run
a set of make files.
I do not want to change the "CC" in the make files.
But , when I say which gcc in the Mx- compile:
It says "/usr/bin/gcc"
I want to use, say "/tools/gnu/gcc". (THe shell from which emacs is laucnhed
points to this gcc! )
Can I configure the emacs to pick the required compiler?

Thanks again,
Nazir
