Hi Corrina

Many thanks for the quick answer. I have a problem locating the NET
package. Have looked in many ftp sites and can't find any NET package in
either Latest or Contrib. Can you help?

Cygwin itself contains a very old implementation of regex which
isn't compatible with any standard I'm aware of.

But the Cygwin net distro contains two packages regex-4.4 and
pcre-3.4 which provide libraries which contain POSIX regex APIs.
If you have installed them (recommended), just include the
correct headers

           regex-4.4:          regex.h
           pcre-3.4:           pcreposix.h

and link with

           regex-4.4:          -lregex
           pcre-3.4:           -lpcre -lpcreposix
