Howto compile gcc-3.3.6 with gcc-4.1?

[Clemens Eisserer]

Hello,

Because I would like to build the recently released openjdk (and also
some still closed parts like the browser-plugin and some
motif-components) I would need a gcc-3.3 installation on my Fedora7
box.

However compiling gcc-3.3.6 with gcc-4.1.0 does not work, gcc-4.1
generates a lot of warnings and finally bails out with:
f/com.c: Auf höchster Ebene:
f/com.c:11080: Fehler: In Konflikt stehende Typen für »ffecom_gfrt_basictype«
f/com.h:236: Fehler: Vorherige Deklaration von »ffecom_gfrt_basictype« war hier
make[1]: *** [f/com.o] Fehler 1


Any ideas how I could get a working gcc-3.3 copy for Fedora7 without
destroying my existing setup?

Thank you in advance, lg Clemens
