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.
