sqrt: DOMAIN error

Talk about reinventing the wheel!  Instead of pouring so much effort
into obsolete versions of software, why not start with the latest
available version (UNIX System V Release 2.0) and improve that?  Then
you could also feed back your improvements to AT&T so everyone could
benefit.

The "sqrt: DOMAIN error" message is what you get by default under
UNIX System V.  You can also supply your own matherr() routine to
allow special handling of math library exceptions; much better than
core dumping!
