# SYNOPSIS | ||
# | ||
# AX_BOOST_IOSTREAMS | ||
# | ||
# DESCRIPTION | ||
# | ||
# Test for IOStreams library from the Boost C++ libraries. The macro | ||
# requires a preceding call to AX_BOOST_BASE. Further documentation is | ||
# available at <http://randspringer.de/boost/index.html>. | ||
# | ||
# This macro calls: | ||
# | ||
# AC_SUBST(BOOST_IOSTREAMS_LIB) | ||
# | ||
# And sets: | ||
# | ||
# HAVE_BOOST_IOSTREAMS | ||
