++# SYNOPSIS
++#
++#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
++#
++# DESCRIPTION
++#
++#   Check for baseline language coverage in the compiler for the C++11
++#   standard; if necessary, add switches to CXXFLAGS to enable support.
++#
++#   The first 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 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.
