Since when printing a warning is deemed a bug in the compiler?  The
warning here is perfectly valid, since it pinpoints a real bug in the
code (which assumed '\xFD' is an unsigned quantity), so gcc did a real
service here.

I don't know much about SGI, but it could be that the default
character type there is different from x86.  Or it could be a bug in
the SGI version of gcc.
