It's a bit late to be discussing these issues, or reworded: I wish that
discussions like this were done a lot earlier.

I'm planning on release WinAVR with GCC 4.2.2. The most major issue that
I see right now is GCC bug #29524
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29524>
I would like to see a patch for this (even if it is not perfect but
works) sometime next week.

Eric
