Tru64 5.1a, but I doubt that matters.  Irix64 does just that same.

What issues?

Yes -- I read this too late -- but what has changed in that area since

Indeed; I've worked on it (insufficiently).  The GNUPro one from the
`The Linux and Tru64 UNIX Portability' (?) CD works, but I've not been
able to extract the sources for it from Compaq^WHP -- I must try

Some of that is problems with system headers that I may have kludges
for already.

Yes, see etc/TODO.  See cc(1) for how to disable specific warnings,
e.g. `-msg_disable ptrmismatch1,promotmatchw', which I have currently.
I mostly used gcc to find such problems, though, and the result is the
same as with cc currently.  [The Compaq compiler supports some gcc
extensions, so testing __GNUC__ may not be optimal.]

What problem is it trying to solve?  I don't understand.  It doesn't
fix Tru64 or affect Solaris, Irix.
