[oe] empathy warnings being treated as errors

[Neil MacMunn]

I'm running into these two errors when I build empathy

I get past this by removing -Werror from WARN_CFLAGS in 
libempathy/Makefile and then hit

Which I work around by removing -Werror from WARN_CFLAGS in src/Makefile

Empathy hasn't changed but I just switched to gcc-4.5 from 4.3.3 so I 
suspect this is where the problem originates. Looking at an old log I 
can see that -Werror was set there too.
