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 <[email protected]> ++# Copyright (c) 2012 Zack Weinberg <[email protected]> ++# Copyright (c) 2013 Roy Stogner <[email protected]> ++# Copyright (c) 2014, 2015 Google Inc.; contributed by Alexey Sokolov <[email protected]> ++# Copyright (c) 2015 Paul Norman <[email protected]> ++# Copyright (c) 2015 Moritz Klammler <[email protected]> ++# Copyright (c) 2016 Krzesimir Nowak <[email protected]> ++# ++# 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.
