[avr-gcc-list] avr-gcc fails to build

[Jason Kyle]

Hi Ormund,

Try a later snapshot or current CVS of gcc, I had success with gcc-20010409
and binutils-010409 (NB avr-libc-20010331 requires a quick touch-up, see
mailing list archive).  Always, always, without fail, try a the latest
available version first :)  Remember that the avr target for gcc is a work
in progress and needs feedback in order to progress, keeping up to date is
important for everyone using this target as there are bug fixes and
optimisations happening often.

Cheers,

Jason Kyle
