You aren't seeing regressions because you're not setting MACOSX_DEPLOYMENT_TARGET during the gcc build. It took me days to puzzle that out why a standalone build of gcc 4.9.2 on darwin14 produced clean test suite results but one under the fink packaging system, which sets MACOSX_DEPLOYMENT_TARGET, produced a huge number of regressions in the fortran test suite. So you definitely do want to back port the configure/libtool.m4 fixes for 4.9.3.
