You do not appear to be wrong.  Although the warning is approopriate,
the error is not.

I'd say that you're right. The AOS 4.3 RT hc compilers all compiled the 
code without problem (except for warnings about not using variable foo).
Pcc on the other hand gave exactly the same complaints as the AIX compiler.

	foo = (void *) &bar;

If the AIX compiler claims to be ANSI (I'm not sure if it does), then
I'd suggest that you do report it as a bug and see if you can get it fixed.

This problem appears only in the AIX/RT C Compiler.  The AIX PS/2
C compiler does allow void pointers to be declared AND used.
However, both the AIX/RT and AIX PS/2 versions of lint choke
on void pointers.

Somebody want to fix this one?
