Two issues bulding ghc 6.4.1

I have encountered two issues trying to build ghc-6.4.1 from the source tarball. 1. (fixed) GNU make v 3.79 does not work (was discussed on irc yesterday: at least two people including myself got this issue), v 3.80 works. If not already in FAQ/wiki perhaps worth including. 2. Error while assembling (or mangling?) ForeignObj.lhs; fragments of make output below (long lines wrapped/truncated, the whole file is too long to post it here but I'll provide it if needed): ======================================================================= ------------------------------------------------------------------------ ../../ghc/compiler/ghc-inplace -M -optdep-f -optdep.depend -optdep-s -optdepp -osuf o -H16m -O -ign <
