Hi Per Arnold, Anatoly,
For some weird reason I can't seem to get these patches on the avr-libc-dev
mailing list. I'm sending these patches to both of you. Can either of you
try to send these to the avr-libc-dev list? I'm going to see if the problem
is on my end, or something with Savannah...
Thanks a lot,
Eric Weddington
