Regex, clitar.c and Autoconf

[David Collier-Brown]

| That would be me; is it enough to know that the headers files exist? If so
| the Autoconf convention is HAVE_<headername>; e.g. HAVE_REGEX_H if
| <regex.h> was found on the system.
| 
| If you also need to do feature tests (e.g. check and see that the regcomp
| works in some particular way) then there isn't any (current) standard
| feature tests for the regex stuff. It is easy enough to write one though.

	The latter is usually necessary: reg* is implemented
	differently by **many** vendors.   Is there a convention
	about how feature-test-names are written?
