gcc hardcoded in build scripts! (ignores the --with-gcc= flag in configure)
NB: this may be a dupe of another issue, but reporting is separately for now
i'm on OS X 10.8 (mountain lion) with xcode 5, ghc comit 23fb7f3b,
I've got a gcc-4.8 installed, though gcc in my path is actually clang (as is typical for xcode 5),
so I configured as ./configure --with-gcc=gcc-4.8
and then I noticed as i'm building, some warnings that mean clang is being called rather than gcc!
heres a relevant snippet of the build transcript
