When doing boostrap.sh process sometimes there is such situation, that some packages compile with one set of flags, some with totally different (like ncurses - it needs -fno-exceptions, and db4 needs -fexceptions - theese flags are opposite so compilation will fail instead, if you put -fexceptions it will fail on ncurses, if "-fno-expections" on db4). I thought to make possible creation of /etc/portage/packages.cflags and /etc/portage/packages.cxxflags files with extra flags for this, so one can add needed flags to selected package. I wrote a patch for portage but I don't know if it wokrs case don't know how to test it. It is in attachment.
Created attachment 54483 [details, diff] patch for portage_const.py. unfotunately - untested
