I just got a nice little piece of info from MKS.
To make an alias for cc to c89, do the following:
shell/ix> ln -s /SYS/HPBIN/C89 /bin/cc
shell/ix> ln -s /etc/c89.ccg /etc/compiler.ccg
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.
