downgrade gcc 4.X to 3.x ?

[LarryT]

Hi all,
I would like to know if there is a way to downgrade a package : i wanna 
compil QEMU on fc5 and qemu is known to crash when compiling with gcc 
4.x ; so i need to install the gcc 3.x compilator.
Is there any workaround please ?
Does this could do the trick  :
rpm -Uhv --force gcc 3.x ?
But i cant find gcc 3.x for fc5 :(
any idea please ?
thx
