I just got a nice little piece of info from MKS. 

To make an alias for cc to c89, do the following: 

<pre>
  shell/ix> ln -s /SYS/HPBIN/C89 /bin/cc
  shell/ix> ln -s /etc/c89.ccg /etc/compiler.ccg
</pre>

This makes cc a legitimate alias for c89 even inside make. I like it because it's one less change I need in the makefiles that come with Unix software.

When making mods to source code, the following two IFDEFs are the standards for identifying:

  --[[SteveElmer]]

__GNUC__ GNU C Compiler

  --[[MarkKlein]]


__hp3000s900 HP3000 Series 900 (i.e. MPE/iX)

For a detailed paper on porting issues in the MPE/iX POSIX environment, see Mark Bixby's paper at http://www.cccd.edu/~markb/porting.html. Mark is one of the most experienced "porters" of applications to MPE/iX and has ported many applications including BIND, Sendmail, Apache, and others..
