--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I think what you're describing or looking for is something completely
different, which might be useful but is not what is present today.

The libstdc++-v3/scripts/check_compile script cannot be turned into what yo=
u're
describing. There's simply no way to get to what you want from a naive shell
script that isn't parallelized, and doesn't understand the dg-* directives =
in
the tests, and only supports a single -std option for all tests.

What we have today is not useful. A replacement would have to be written fr=
om
scratch anyway, so ripping it out entirely has no downside as far as I can =
see.=
