The version issue was that the old code generator made use of a rather nasty
Perl script (commonly known as the Evil Mangler) to peephole optimize gas
output for the STG, and that script breaks on Perl > 5.8.x. In recent GHC
versions, this code generator (-fvia-C) is strongly deprecated but still
present; it is likely to be removed in GHC 7.2.
In short, it would be best to leave it dependent on perl5.8 for people who
need to use -fvia-C.
