COMMAFMT.C
public domain by Bob Stout, bug fixes by Mark Kamradt
Notes: 1. Use static buffer to eliminate error checks on buffer overflow
and reduce code size.
2. By making the numeric argument a long and prototyping it before
use, passed numeric arguments will be implicitly cast to longs
thereby avoiding int overflow.
3. Use the thousands grouping and thousands separator from the
ANSI locale to make this more robust.
