Uninstall gcc 3.1

[Carlos Rubio Nievas]

Is there any way to uninstall gcc 3.1 in this system?:

   -Output from running srcdir/config.guess.

        i686-pc-linux-gnu

   -The output of gcc -v for my old gcc.

        Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
        Configured with: ../confirgure : (reconfigured) ../configure
        Model of threads: single
        gcc version 3.1

   - Distribution name and version:
        Red Hat Linux 8.0 upgraded from version 7.2 (Enigma)

   - The version of the Linux kernel:
        Linux morpheo 2.4.18-14 Wed Sep 4 13:35:50 EDT 2002 i686 i686 i386 
GNU/Linux

   - The version of glibc I used:
        glibc-2.2.93-5

I have tried everything...the last thing was upgrading the operating system 
from 7.2 to 8.0 but it is still using gcc 3.1 and I have the same compilation 
errors (don't find header files...)
 
I hope this is enought information to solve the problem. I'm looking forward
to your response. Thanks a lot,

Carlos
