You can do this: add a #define (via configure.ac) when building with
--enable-build-with-cxx, like AC_DEFINE([GCC_BUILT_WITH_CXX]), and use

#include "config.h"
#if defined __cplusplus&&  !defined GCC_BUILT_WITH_CXX
extern "C" {
#endif

I believe it is a mistake to build with a C++ compiler and decide NOT to take
advantage of the additional checking of function calls.

Yes, the above sketch would do what you said: "undo" Duncan's patch if GCC was built with a C++ compiler.
