dnl @synopsis AX_BOOST_IOSTREAMS
dnl
dnl Test for IOStreams library from the Boost C++ libraries. The macro
dnl requires a preceding call to AX_BOOST_BASE. Further documentation
dnl is available at <http://randspringer.de/boost/index.html>.
dnl
dnl This macro calls:
dnl
dnl AC_SUBST(BOOST_IOSTREAMS_LIB)
dnl
dnl And sets:
dnl
dnl HAVE_BOOST_IOSTREAMS
dnl
dnl @category InstalledPackages
dnl @category Cxx
dnl @author Thomas Porschberg <thomas@randspringer.de>
dnl @version 2006-06-15
dnl @license AllPermissive
dnl
dnl Modified by me to make using iostreams the default and to fail if
dnl the user tries to disable it. Also changed linking to check for
dnl libboost_iostreams-mt instead of libboost_iostreams and to fail
dnl if the library can't be found.
