Update to a recent snapshot. Among others, this fixes an issue with
the generation of code that fed up recent versions of gas. The
pseudo-symbol _PC_ is now completely eliminated from the generated
code, and replaced by the location counter `.'.
Update to version 2002.09.01. Included are a couple of private
patches that were floating through the avr-gcc and avr-libc
mailinglists, just for the time being until they might have been
integrated into gcc's CVS.
Portname changed from dashes in the snap date to dots so portupgrade
doesn't get confused about it. Thanks to Brian Dean for the hint.
