Just having a discussion on g++ list about 4.3 two days ago g++-4.3 is not able to compile older applications, which means everything older then may be two years ago depending on how isoC++ programmers have written the code. I'm actually considering removing 4.3 right now otherways I have to export CXX and CC everytime I do compile and this is annoying. regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
