compile gcc with other libc

[Fabiano Ramos]

Hi.

 I've been trying to use two different versions of glibc on my system. 
I have the 2.3.2 and compiled and installed an older version, 2.2.5 under
/usr/local/glibc-2.2.5.   My objetive is to compile another version of gcc,
which will by default use this new glibc. This way, changing glibc's will
be just a matter of compiling with one gcc or the other.
 Is this approach correct? Can anyone help to compile gcc using this new
installed glibc?

TIA,
