  Well, the main thing it would have done is make an executable called "gcc"
available in your $PATH, which could well solve any number of failures in a
configure script if by any chance you forgot to specify "CC=gcc-4 CXX=g++-4"
the first time you tried to configure it....

Can't think of a witty .sigline today....
