dnl @synopsis AX_BOOST_DATE_TIME
dnl
dnl This macro checks to see if the Boost.DateTime library is
dnl installed. It also attempts to guess the currect library name using
dnl several attempts. It tries to build the library name using a user
dnl supplied name or suffix and then just the raw library.
dnl
dnl If the library is found, HAVE_BOOST_DATE_TIME is defined and
dnl BOOST_DATE_TIME_LIB is set to the name of the library.
dnl
dnl This macro calls AC_SUBST(BOOST_DATE_TIME_LIB).
