Would an ugly but pragmatic approach be possible? e.g. if the first line of the
translation unit is "/* confdefs.h */ then assume GCC is being invoked by
configure, and only warn instead of giving an error.

But don't do that if -Werror=implicit-function-declaration was used explicitly,
because maybe the configure test is actually trying to detect that error.
