GHC-6.4.2 initial compiler

 gcc (GCC) 3.4.4 (Gentoo 3.4.4, ssp-3.4.4-1.0, pie-8.7.8)

 making ghc-6.5-20060703 snapshot

 download, unpack, configure with custom --prefix, and `make`
 eventually errors with:
 {{{
 ../compiler/ghc-inplace -H16m -O -optc-O2 -static -I. -#include
 HCIncludes.h -dcmm-lint   -#include posix/Itimer.h  -c PrimOps.cmm -o
 PrimOps.o
 Prologue junk?:         .globl retryzh_fast
         .type   retryzh_fast, @function
 retryzh_fast:
         mfcr 12
 make[1]: *** [PrimOps.o] Error 255
 make: *** [stage1] Error 1
 }}}

 Adding `GhcRtsHcOpts=-optc-O1` to mk/build.mk resolved this error upon
 running `make` again.
