Allright. I never stumbled over DR code, and that's prolly the reason why I did not recognize it (or possibly I thought that DRs are to be under -std=c++0x). Carved into synapses for the future. > For some time, many years ago, that _GLIBCXX_RESOLVE_LIB_DEFECTS was an > actual macro and we tried to deliver both a vanilla C++98 and an amended > version, depending on that macro, but it became quickly unmanageable, for > various reasons (what to do with exported symbols, ODR, etc). I already wanted to ask about a switch and it's non-presence, but seeing the number of DRs I already guessed it would be unmaintanable. > Besides, > according to the ISO rules, resolved DRs *are* part of the Standard in law, > even if a completely new document does not exist yet. That's both interesting and valuable knowledge, as I am nitpicky myself at times :D Thanks for sharing your time :)
