The message at http://gcc.gnu.org/ml/java/2006-05/msg00151.html says to apply 
them to a stock 4.0.2 source tree. To do so, download a 4.0.2 source tarball, 
unpack it, and apply the patches from the directory that contains the 
gcc-4.0.2 directory with 'patch -Nup0 < gcc-4.0.2-osx.diff' and then, follow 
the usual build procedures.

The 'trunk' means the main gcc development trunk, at the moment, that is gcc 
4.2.0, I believe.
