That seems odd. Not really. The use of the no-runtime-stubs.patch patch would keep the tests in config/tls.m4 for working properly as it breaks the ability of the xgcc compiler from accessing the emutls support calls residing in libgcc_ext.10.4/5. > > > Why is it so critical for MacPorts to eliminate the linkage on > > libgcc_ext.10.4/ libgcc_ext.10.5? > > Because it doesn't exist. This is the wrong approach. You shouldn't be trying to gut libgcc_ext from libstdc++-v3 but rather creating an additional splitoff for libgcc_s/libgcc_ext.10.4/5 so that they are kept at the latest level.
