There's no easy way to fix that from configure.bat in a simple and portable way; the next best fix is just err out with a clear message when running configure.bat so the user can react immediately, instead of getting a not-so-clear error or warning during compilation. I've implemented the check only for GCC because I don't have access to MSVC; but it should be trivial to add if MSVC has some command option similar to GCC's -Werror (turn any warning into an error). =C2=A0 =C2=A0 Juanma ------------=_1285197662-21747-1 Content-Type: message/rfc822 Content-Disposition: inline Content-Transfer-Encoding: 7bit Received: (at submit) by debbugs.gnu.org;
