Or maybe, modify the definition of AC_LANG_WERROR itself, allowing it to
accept an optional ON/OFF argument? Then:
- AC_LANG_WERROR([ON]) would have the same effect as the existing
behaviour, and would be the default for backward compatibility,
so continuing to support use without any argument.
- AC_LANG_WERROR([OFF]) would cancel the effect of any prior use
of AC_LANG_WERROR([ON]), (or would simply have no effect if not
previously ON, and could be silently ignored).
Just a thought, but seems somehow cleaner than having two complementary
macros, IMHO.
