Per a discussion on the devel telecon a week or two ago, I have refactored the opal/util/if.c code into a static framework (ala the installdirs implementation) so that the various cases are dealt with in configure.m4 instead of a mass of interwoven #if-#else clauses. Jeff will undoubtedly do some cleanup of the configury magic, but the basic functionality is ready for initial review.
For those who care, please clone and check the code at http://bitbucket.org/rhc/ompi-if to ensure that the correct opal/mca/if components are being built for your environment, and that the discovered interfaces are correct. Please let me know (up or down) so we can get a feel for how close we are to bringing this back to the trunk. Thanks Ralph
