(_AC_CHECK_DECL_BODY): Call it once per language; treat warnings as errors when its verdict indicates that. * tests/semantics.at (AC_CHECK_DECLS): Add a macro call that relies on the new semantics. Avoid -Wmissing-variable-declarations warnings. * doc/autoconf.texi (Generic Declarations): Document the implications. * NEWS: Mention this change. |
