The macro # requires a preceding call to AX_BOOST_BASE. Further documentation is # available at . # # This macro calls: # # AC_SUBST(BOOST_IOSTREAMS_LIB) # # And sets: # # HAVE_BOOST_IOSTREAMS # # LICENSE # # Copyright (c) 2008 Thomas Porschberg # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
