We believe the runtime behavior is sufficiently dangerous to warrant a conservative view that any call to a function will be a call that gets executed at runtime, hence a definitive signature mismatch is something we feel comfortable diagnosing (in some form) by default.
As long as these diagnostics by default do not cause the compiler to exit with nonzero status, we should be OK with Autoconf-generated 'configure' scripts. Although there will be problems with people who run "./configure CFLAGS='-Werror'", that sort of usage has always been problematic and unsupported by Autoconf, so we can simply continue to tell people "don't do that".
