will gcc delete other gcc?
 

What would happen if I installed an older verion of gcc, without any special configure options. Would it install on top of(delete) any current version of gcc?

I believe by default it'll put itself in /usr/gnu-<machine>/gnu-bin/<version-number> so it shouldn't delete the old version, but it might delete thing symbolic links to /usr/gnu-<machine>/bin or something. Is there a specific reason you need to get an older version?

I was just trying to sort some stuff out. I noticed I have a bianary in both /usr/bin and /usr/i686-pc-linux-gnu/gcc-bin/3.2 called gcc, when I compile somthing which one is used?

Probably the one in /usr/bin. Is the other directory even in your path? BTW, if you use portage to install another GCC it will overwrite the one you have, just so you know.

thanks for all of your input.
