There have been several articles recently about how some code from Suns
does not port easily to HP-UX.  The main reason seems to be HP-UX is
System V and Sun is BSD.  Now coming up is POSIX.  I haven't seen
the specs yet, but I get the impression that POSIX is more like
System V.

Can someone comment on this?  In particular, what systems are
currently closer to POSIX (i.e. which programmers are going to have
to change more to be POSIX compatible)?  I know HP is committed to
standards (so is Sun; there are so many standards to choose from ;-),
but does anyone know when HP, Sun, etc might reasonably be POSIX
compliant?  When that does happen, will some of these problems go
away?
