I saw this morning that the Gcc project has made a pre-release cut, announced here:

http://gcc.gnu.org/ml/gcc/2005-04/msg00479.html

It is very easy to install this version:

1) tar jxf gcc-4.0.0-20050410.tar.bz2

2) cd gcc-4.0.0-20050410

3) mkdir objdir

4) cd objdir

5) ../configure --disable-shared --enable-languages=c,c++

6) make > /dev/null

7) (su)

8) make install

The '--disable-shared' flag will build libstdc++ statically, so that we can deliver binaries to others without adding a dependency on the latest version.
