Hi,

I maintain the Gnoduino PPA for Ubuntu:
https://launchpad.net/~pmjdebruijn/+archive/gnoduino-unstable

While working on a package for Ubuntu Quantal (which has gcc 4.7), I
noticed sketches which use WiFi.cpp seem to trigger a GCC bug:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50925

Apparently it can be worked around by passing -fno-caller-saves to
avr-gcc and avr-g++.

I haven't extensively tested any sketches (yet) using that fix, but at
least the sketches compile again.

While I haven't checked myself, it seems quite likely that Debian's
Arduino package may be affected by this issue was well. I discovered
this by building the ConnectWithWPA example.

Regards,
Pascal de Bruijn
