GCC 3 works fine with GHC on x86.  On Sparc, we had a couple of problems
that were sorted out post-5.04 and the fixes will be in 5.04.1.

None of this affects .hc files themselves - any problems are generally
confined to the Evil Mangler(TM).  So although the 4.08 .hc files should
still work fine, you might need to back-port some of the fixes to the
mangler into 4.08 in order to bootstrap.
