If the question is "How can I differentiate multiple gcc versions, when
compiling from source?" then this may do the job:

MULTIPLE GCC versions:
   The easiest way to do this is to configure the new GCC with
   --prefix=/usr/local/gcc and the older gcc2 with --prefix=/usr/local/gcc2.
   Build and install both compilers. Then make a symlink from /usr/local/bin/gcc
   to /usr/local/gcc/bin/gcc and from /usr/local/bin/gcc2 to
   /usr/local/gcc2/bin/gcc. [From the distribution's FAQ]
