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