AX_BOOST_REGEX
This macro checks to see if the Boost.Regex library is installed. It also attempts to guess the currect library name using several attempts. It tries to build the library name using a user supplied name or suffix and then just the raw library.
If the library is found, HAVE_BOOST_REGEX is defined and BOOST_REGEX_LIB is set to the name of the library.
This macro calls AC_SUBST(BOOST_REGEX_LIB).
