I would rather this claim were backed up by some refmac tests - preferably a 
full run of my autotest suite. (You can download it and mmtzlib separately at 
the bottom of my CCP4 page). My best guess at the moment is that at least 
refmac5 will be broken in your build.

I've now built on 7 compilers on 4 distros, and both my experience and 
Garib's is that refmac5 fails even with gcc 3.0.1 unless you add the 
fno-automatic flag, although 3.0.1 is certainly much better than the 2.96 
versions.

The only compilers I know of on which the official distribution works without 
fixes are ecgs and gcc 2.95.*. (i.e. not on any version of Red Hat released 
this millenium).
