sockaddr_in - seems to be a good indicator) * disable util/if code if no inet devices (again, no sockaddr_in) * add enable/disable flag to disable stacktrace pretty-print code (defaults to enabled). Seems there's something funky going on with the preprocessor on Red Storm that was causing problems - this was the easiest fix * clean up a bunch of the configure.m4 files to remove bogus comments, properly comment them, fix the dumb logic for happy/unhappy * Create a macro for testing both header and library for a package, since we seem to do this kind of test quite often. Handles the -I and -L search paths properly (including stripping out /usr and /usr/local if not needed) * Converted mvapi components to configure.m4, using the nice new ompi_check_package macro (above) This commit was SVN r6454.
