---------------------------------+------------------------------------------
 On my OS X Mountain Lion machine, while building HEAD with GHC 7.4.2 as
 the bootstrapping compiler, the build eventually fails like so:

 {{{
 $ make
 ===--- building phase 0
 /usr/bin/make -r --no-print-directory -f ghc.mk phase=0 phase_0_builds
 make[1]: Nothing to be done for `phase_0_builds'.

 }}}

 This is from a checkout from Friday, August 3rd 2012. It looks like a bug
 in the DIY linker. Initially I thought it might be fixed by Luite's patch
 in #7040, but it is not. The build is also completely littered with
 warnings during compilation from the assembler:

 {{{
 /var/folders/6x/2_5h95jx2kqgpbnk0cpg1vd00000gn/T/ghc67149_0/ghc67149_0.s:970:0:
     section difference relocatable subtraction expression,
 "_dphzmprimzmseqzm0zi6zi0zi1_DataziArrayziParallelziUnliftedziArrayArray_MutableArrayArray_info"
 minus
 "_dphzmprimzmseqzm0zi6zi0zi1_DataziArrayziParallelziUnliftedziArrayArray_MutableArrayArray_info_dsp"
 using a symbol at the end of section will not produce an assembly time
 constant
 }}}

 I imagine this is due to some unforseen toolchain updates in XCode 4.5.
 I'll look into supressing these warnings with a patch.
