Using the compiler is moderately, there's an option to gcc to use another 
version, the executables are in /usr/lib/... IIRC. The problem I have run into 
is that the header files aren't properly separated, and you have to get the 4.3 
headers, plus the kernel headers, off into some directory you can use with -I to 
get correct behavior. I have some old code which uses vararg and won't compile 
under current tool chains. After a lot of hassle I just keep a VM with FC4 or so 
running to use the app. I have source, but it's 10's of k of someone else's 
code, and I have no incentive to convert it.

Note that you are probably lucky and can happily use the default headers. If you 
are really lucky you can
   "yum list compat*"
and there will be an old compiler available for you at the right level. I 
haven't looked.
