I do this by setting $PATH.

BTW, if you build your software "--prefix=...", you don't even need root
access on the box.  No need to touch /usr/local/bin.

I do this by setting $PATH.  Yup, I have a little shim directory,
with a script in it named "gcc" that just calls the real compiler
that I want with the options I want.  Ewww, it's gross!  But it
gets my testing done.

If I just want to adjust the version of gcc that I use, I just
make sure that I've configured that version of gcc using a
convenient "--prefix=/.../.../..." option, and that I've actually
installed that version of gcc.  There's lots of code in dejagnu
to test built-but-not-installed yet gcc trees, but it doesn't
help me any.

$PATH works really well for selecting the gdb to run.
