Subject: Re: [OMPI users] Problem compiling 1.7.2 on Mac OS 10.8 with gcc 4.8
From: Hugo Gagnon (opensource.openmpi_at_[hidden])

My apologies; I just realized that I was compiling with the LLVM
dragonegg 3.4 GCC plugin, which apparently does not support all of GCC
yet. Hopefully this will be of some help to someone in the future!
