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_FILESYSTEM_LIB) # # And sets: # # HAVE_BOOST_FILESYSTEM # # LICENSE # # Copyright (c) 2009 Thomas Porschberg <thomas@randspringer.de> # Copyright (c) 2009 Michael Tindal # Copyright (c) 2009 Roman Rybalko <libtorrent@romanr.info> # # 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.
