Hi everybody,

I just tried to bootstrap gcc-4.6.0 on Solaris10 and got this:

I fixed this by copying the fatal() from gcc/errors.c to gcc/diagnostic.c.
However, it is not clear to me why the link succeeds on Debian Lenny (x64) and
fails on Solaris10.

I also recognized that there is some code duplication in diagnostic.c and
errors.c, maybe they're candidates for a cleanup?

Best wishes
