Thanks. I don't remember, do you have a specific interest in the AVR32
architecture support?

The thing is that apparently, the AVR32 gcc version we're using (gcc
4.2.x) doesn't build anymore with recent host gcc version (I think
Gustavo tested with gcc 4.6, and it doesn't build). Generally speaking,
the fact that we have to use old, patched, versions of gcc, binutils and
uClibc is severely problematic to support this architecture on the long

Back in November, I got in touch with the people who were active on the
AVR32 architecture a few years back (Hans-Christian Egtvedt and Håvard
Skinnemoen), but they no longer work for Atmel and therefore don't know
what Atmel plans are regarding the AVR32 architecture.

Therefore, I'm wondering if we shouldn't mark this architecture as
