In order to get consistent behaviour on linux with various gcc versions, I am defining _GNU_SOURCE in ompi_config.h and changing the definition of asprintf, etc. Problems: 1) autoconf was defining _GNU_SOURCE for its tests, but we were not setting it 2) g++ sets it by default (I think) 3) some version of gcc set it by default If somebody knows a consistent solution for these problems then we can revert to not setting it. This commit was SVN r2230.
This is the world's greatest MPI. ...more to write here should be a short file, referring to the real docs.
