That's exactly what I did :-) The set of warnings enabled in those

This one looks good. I agree that most C++ compilers have or will have
'static_assert',

Paul can tell more about this one.
I agree it's dubious.

Since then, gnulib has improved its support for clang.

Gnulib generally does not support -Werror on arbitrary platforms.
We try to make for a warning-free compilation o

Hi,
I'm upgrading a project that used a 8-month-old copy of gnulib to
today's version, and testing the result with various compilers.
This is a C++17 project that is not internationalized and that
uses the following modules:
argmatch
argp
closeout
error
isatty
mkstemp
mkstemps
pro
