Installing Multiple Instances of GCC (4.0, 4.1)

What's the best practice for installing 2 versions of GCC on
Fedora?
E.g. I need 4.0 for backwards compatibility when compiling
kernel
modules.

In Debian, for example, you can just install both packages.

gcc-4.0 - The GNU C compiler
gcc-4.1 - The GNU C compiler

When I tried doing something similar on Fedora, I got
package
conflicts.
