- Delete unnecessary header files using contrib/check_unnecessary_headers.sh after applying patches, that include headers, being "lost" due to inclusion in one of the now deleted headers... In total 817 files are touched. In ompi/mpi/c/ header files are moved up into the actual c-file, where necessary (these are the only additional #include), otherwise it is only deletions of #include (apart from the above additions required due to notifier...) - To get different MCAs (OpenIB, TM, ALPS), an earlier version was successfully compiled (yesterday) on: Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled This commit was SVN r21096.
