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 no added switch, and then 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. +# +# If the fourth argument is an optional CXX/CXXFLAG/CPPFLAG suffix, e.g. +# "_FOR_BUILD" or "_FOR_TARGET". +# +# +# 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, 2015 Google Inc.; contributed by Alexey Sokolov <sokolov@google.com> +# Copyright (c) 2015 Paul Norman <penorman@mac.com> +# Copyright (c) 2015 Moritz Klammler <moritz@klammler.eu> +# Copyright (c) 2016, 2018 Krzesimir Nowak <qdlacz@gmail.com> +# Copyright (c) 2019 Enji Cooper <yaneurabeya@gmail.com> +# Copyright (c) 2020 Jason Merrill <jason@redhat.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.
