* The `patch' command is now part of stdenv, so it no longer needs to
be passed to derivations that need to apply patches. * GCC 3.4 is now the default compiler (old GCC renamed to `gcc-3.3'). * The temporary GCCs built during the stdenvLinux bootstrap are now built without C++ support and without profiling. * Remove fixincl in GCC 3.4 to prevent a retained dependency on the previous GCC. * Always set $prefix in setup.sh, even when there is no configure script. svn path=/nixpkgs/trunk/; revision=1444
