this is :

CC=/path/to/cc ./configure

this is equivalent to:

CC=/path/to/cc
export CC
./configure
unset CC

Ie the CC variable is exported in the shell that configure runs in but
not yours, handy trick once you understand it, totally confusing to a
DOS programmer :-)

This does NOT work with csh shell derivatives.
