I see the problem; I missed updating a variable in my patch. I verified this
by just configuring OMPI on my Mac the same way you did (or something close to
it):
./configure --disable-mpi-fortran CC=clang CXX=clang++ CFLAGS="-Os -w -pipe
-march=native -Xclang -target-feature -Xclang -aes -Qunused-arguments
-mmacosx-version-min=10.8 -finline-functions -fno-strict-aliasing -isystem
/usr/local/include" ...
With my new patch (below), this now works properly -- both -Xclangs are
preserved. I'll go commit this to the OMPI SVN trunk and bring it over to v1.6
and v1.7.
