Our native library doesn't have drand48, hsearch or getopt, and tempnam is
just a throwback to the days before sprintf.

I don't use popen either. It doesn't run on non-UNIX systems.

I don't even have MAKE on my IBM-PC. And before you flame me about using
an IBM-PC, it's a requirement of the job. The remainder of your message
suffers from the same flaws. Not everyone has access to all those neat
bells & whistles... this group is for 'C' standards, not UNIX standards.
'C' isn't an integral part of UNIX any more...

Semiflame: And SV isn't automatically THE STANDARD ENVIRONMENT either.
