[avr-gcc-list] AVR toolset bugs and patches pending

[E. Weddington]

Hello All!

[This has been CC'd to the official AVR GCC maintainers, and those 
people who are known to have FSF paperwork filed.]

Below is a list of known GCC bugs that affect the AVR target, hopefully 
in some kind of order of importance (at least IMHO, YMMV). I especially 
want to point out GCC bug #15417, which says that currently AVR GCC 
cannot be built for the upcoming 3.5 (HEAD). Any work to get that one 
fixed would be very appreciated. Other noteworthy items:
Bug #14064 has a potential fix mentioned in the comments. It needs 
confirmation and a commit.
Any help to confirm the unconfirmed bugs #16563 and #16884 would be 
appreciated.

Also, there is a patch at avr-libc that needs attention:

avr-libc patch #2923
<http://savannah.nongnu.org/patch/?func=detailitem&item_id=2923>
This adds new AVR decvices to the toolchain. Requires patching binutils, 
gcc, and avr-libc.

Thanks
