The canonical operating systems to think about are pre-Solaris SunOS,
and HP/UX.  Both ship with a K&R C compiler (although I admittedly
don't know about the most recent versions of HP/UX).  Both are
reasonably widely used.  Both come on machines easily powerful enough
to compile gcc.

I recommend a simple approach for the binutils: stick to K&R until gcc
changes.
