Yes.  Fun, isn't it?  Surprising how many commercially-shipped UNIX
systems have yet to acknowledge the existence of X3-159.  (Indeed, if I
get enough mail saying who supports ANSI C and who does not, I'll post a
summary.  But you'll have to over-ride the Followup-To: line above if
you want to post to comp.lang.c on this topic.)

But anyway, for A/UX there are, to my knowledge, three unsatisfactory ways
out of the bind:

1.  Compile programs using a (more) compliant Macintosh C complier, and
    run them under A/UX as Macintosh applications.  However, this makes
    them ``un-UNIX-like'' -- they don't have real command lines, can't
    be used in pipelines, and so on.

2.  Download gcc for A/UX.  It's available from several places -- none
    of them sanctioned by the Free Software Foundation, as FSF does not
    like Apple.  To quote bits of John L Coolidge's message
    <1991Jan30.002109.5728@julius.cs.uiuc.edu>:

     The problem I've found with gcc is that Apple's headers and
     libraries are not ANSI-compliant, so gcc does not like them at all.
     What's the way around this, folks?  (I probably wasn't paying
     attention when it was explained.)

3.   Get a commercial or freeware ANSI to ``common usage'' C translator.
     Mindcraft, at (800) LE POSIX (really) or (415) 323 9000 can sell
     you one.  No doubt others exist.  This approach to skirting your
     problem will probably work, but, boy, does it feel tacky!

Hmmm.  Put it this way.  Most other suppliers seem to have a greater
commitment to shipping a modern UNIX does than Apple.  On the other hand,
Apple does ship an awful lot of functionality for a single, not
unreasonable all-in price with A/UX.  Most other suppliers charge extra
for a C compilation subsystem.  Maybe you get what you pay for.  (Unless
you go to FSF?)
