I do not use those flags in /etc/make.conf! /etc/src.conf is supposed to target ONLY the /usr/src world, not the ports - this is as I interpret the man page for /etc/src.conf and it would be logical. But this rule/thinking seems to be broken by some includes from /usr/ports/Mk ingredients. I can assure that I didn't switch anything to build the ports but rebuilding world and then restarting building. Something must have changed since then in the logic of how libc++ slipped in instead of of libstdc++. What I did was a "make delete-old-files", which deleted several GNU gcc stuff on all CURRENT boxes. I did not see that any lib got killed after I tried "make delete-old-libs". And I did not check whether libstdc++ is still being built. There are many other occasions where now c++ errors occur and I guess those ports need to be reported in one by one via PR?
