If necessary, add switches to CXX and # CXXCPP to enable support. VERSION may be '11' (for the C++11 standard) # or '14' (for the C++14 standard). # # The second argument, if specified, indicates whether you insist on an # extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. # -std=c++11). If neither is specified, you get whatever works, with # preference for an extended mode. # # The third argument, if specified 'mandatory' or if left unspecified, # indicates that baseline support for the specified C++ standard 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_CXX${VERSION} if and only if a # supporting mode is found. # # LICENSE # # Copyright (c) 2008 Benjamin Kosnik # Copyright (c) 2012 Zack Weinberg # Copyright (c) 2013 Roy Stogner # Copyright (c) 2014, 2015 Google Inc.; contributed by Alexey Sokolov # Copyright (c) 2015 Paul Norman # Copyright (c) 2015 Moritz Klammler # Copyright (c) 2016, 2018 Krzesimir Nowak # Copyright (c) 2019 Enji Cooper # # 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.
