# SYNOPSIS
#
#   AX_CXX_COMPILE_STDCXX_17([ext|noext], [mandatory|optional])
#
# DESCRIPTION
#
#   Check for baseline language coverage in the compiler for the C++17
#   standard; if necessary, add switches to CXX and CXXCPP to enable
#   support.
#
#   This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
#   macro with the version set to C++17.  The two optional arguments are
#   forwarded literally as the second and third argument respectively.
#   Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
#   more information.  If you want to use this macro, you also need to
#   download the ax_cxx_compile_stdcxx.m4 file.
