Further documentation is available at # . # # This macro calls: # # AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS) # # And sets: # # HAVE_BOOST # # LICENSE # # Copyright (c) 2008 Thomas Porschberg # Copyright (c) 2009 Peter Adolphs # # 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.
