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_SYSTEM_LIB) # # And sets: # # HAVE_BOOST_SYSTEM # # LICENSE # # Copyright (c) 2008 Thomas Porschberg <thomas@randspringer.de> # Copyright (c) 2008 Michael Tindal # Copyright (c) 2008 Daniel Casimiro <dan.casimiro@gmail.com> # # 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.
