error: attempt to use poisoned "SIG_USART0_RECV"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile any sketch (.ino). I tested with Blink example.

What is the expected output? What do you see instead?
The compilation ends with error.

Downgrading to gcc-avr 4.3.5 (from Debian stable) solves the problem.

What should these signal names be replaced with?  What versions of avr-gcc / 
avr-libc do those replacements work with?

In more recent avr-libc implementations, the SIGNAL macro and concept is 
replaced by the ISR macro, and the SIG_xxxx names replaced by xxxy_vect values. 
 (presumably, to avoid conflicts with posix-style signals.)  The current 
Arduino code is actually quite a mix, using SIGNAL some places, ISR in others, 
and using xxxy_vect isr names with the SIGNAL macro...

Attached are diffs (from current sources) that should fix this.
Compiles of ASCIITable on Mac yield identical binaries with and without this 
patch; I haven't actually tested with newer compilers.

Attached is a patch from the 1.0.1 release that should fix this. Code builds 
properly with avr-libc 1.8.0, avr-gcc 4.7.2 and avr-binutils 2.22. It now 
depends on avr-libc>=1.4.0.

However, I have not verified that the binaries are correct--I have no reason to 
believe that they aren't, but I haven't verified it.

That is to say that Bill Westfield's patch (comment 3) does NOT actually build 
with a new avr-libc.

Fixed, it will be available on next releases (1.0.5 and 1.5.3)

Thanks for your patches.

patch from comment #4 works like a charm.
needed it for patching sanguino core (644 port).
thank you!

after downloading this sig-patch.diff file where should it be placed or what 
should be done with it?
