If neither is specified, you get whatever works, with # preference for an extended mode. # # The second argument, if specified 'mandatory' or if left unspecified, # indicates that baseline C++11 support is required and that the macro # should error out if no mode with that support is found. If specified # 'optional', then configuration proceeds regardless, after defining # HAVE_CXX11 if and only if a supporting mode is found. # # LICENSE # # Copyright (c) 2008 Benjamin Kosnik <bkoz@redhat.com> # Copyright (c) 2012 Zack Weinberg <zackw@panix.com> # Copyright (c) 2013 Roy Stogner <roystgnr@ices.utexas.edu> # Copyright (c) 2014 Alexey Sokolov <sokolov@google.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.
