--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> 2011-10-22 16:40:26 UTC ---
This is caused by a function naming conflict: output_bb is defined in both
pa.c and gimple-streamer-out.c.  It's a mystery how this worked at all.

gcc-4.5 and 4.6 are also affected.

Guess I'll change the target.

Diego, any reason why you didn't prefix those public functions in
gimple-streamer.[ch]?

I have a patch to prefix the public functions in the pa backend which  
I will
install soon.
