Hi;
I took a bunch of patches that were merged into the GCC 4.1 branch
(under GPLv2) and prepared a patch for merging them into our base
gcc. These are supposed to be bug fixes only.
You can get the patch here:
http://people.freebsd.org/~pfg/patches/patch-contrib-gcc
And, for those really interested, the log is here:
http://people.freebsd.org/~pfg/patches/gcc41-pr-log
It may be my imagination but the patch seems to be causing more
warnings than usual and it breaks the kernel here:

Other stuff I tested (Apache OpenOffice) builds fine.
