See http://gcc.gnu.org/gcc-4.3/porting_to.html: many of the .cpp (and one .h and .yy) files lack some import statements which make the newest version of gpp hiccough. Mostly this is about #import <cstring> #import <cstdlib> #import <algorithm> There are also numerous warnings. Of course the user can repair these himself, but it would seem seater to do this at the source... Thanks, Arend
