- Detect presence of a POSIX-compatible regex interface in configure,
  and omit Text.Regex.Posix (and hence Text.Regex) if it is missing.
  ToDo: pull in a suitably-licensed implementation of POSIX regex
  to be used in the event that the system doesn't supply one.

- Rename old HaveRegex to HaveGNURegex.
