7#   AX_CXX_COMPILE_STDCXX_17([ext|noext], [mandatory|optional])
8#
9# DESCRIPTION
10#
11#   Check for baseline language coverage in the compiler for the C++17
12#   standard; if necessary, add switches to CXX and CXXCPP to enable
13#   support.
14#
15#   This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
16#   macro with the version set to C++17.  The two optional arguments are
17#   forwarded literally as the second and third argument respectively.
18#   Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
19#   more information.  If you want to use this macro, you also need to
20#   download the ax_cxx_compile_stdcxx.m4 file.
