I have problem with linking ... gcc-3.2.2

[krasnal]

 I have already compiled gcc-3.2.2
 It is in /usr/local/gcc-3.2.2
 what I have change to use it parrelly with gcc-2.96 (default in RH 7.3)
 I have changed PATH=/usr/local/gcc-3.2.2/bin:$PATH
 and I'd ask you what else I have to change because my programs did't
linking
 correctly

 Thank a lot
