Snapshots track the 3.1 branch, probably until 3.1.1 is released...

Sorry for any inconvenience, but 3.2 really is required - it's not just
the version number.  GCC 3.1 uses old ld emulations, and these don't work
with the new avr-libc, resulting in confusing linker error messages.
You could work around that by adding -Wl,-m,avr2 to override the default
which is -m avr85xx, etc. but I haven't really tested this.

Use CVS to get the current sources directly from the CVS repository
(not as a tarball).  See http://gcc.gnu.org/cvs.html for details.

Hope this helps,
