 ghc 7.6.3 does not compile on OS X 10.9 (as of DP5).

 There are a few issues that seem to be causing this:

 1) gcc is no longer available and the clang compatibility patches of
 http://ghc.haskell.org/trac/ghc/ticket/7678 are not included in 7.6.3.

 2) There is some sort of bug that causes mkdirhier.sh to fail in some
 cases.

 3) There is another bug when compiling RtsProbes.d with DTrace. The
 problem seems to be triggered by the inclusion of stdint.h. #undef-ing
 HAVE_STDINT_H only for the compilation of RtsProbes.d (which then includes
 inttypes.h instead)  seems to work for some reason. A better solution may
 be possible from someone who understands the DTrace machinery better.

 The issue has has been discussed here:

 https://github.com/mxcl/homebrew/issues/20546

 I have come up with a tentative patch that fixes problems (2) and (3) here
 (and also pasted below):
