Yes, I built ghc-6.8.3 with gcc-4.2.4 and it builds ok, it just takes
two days to do so. So it's not really usable for ghc development. It may
be fine for using ghc, but not for hacking ghc.

In future it should not matter once we get the -fasm route working. Then
we'll only need gcc to build the rts and to assemble things, not to
compile massive .hc files.
