I think it is extremely unlikely to trigger there. (That part uses no system-specific code.) Using -Werror for libgfortran's C code would be nice, but it fails too often. (I tried it once.) Thus, libgfortran's C code is compiled without -Werror by default - even without an explicit --disable-werror. Thus, I think your issue is rather hypothetical and I don't think it makes sense to fix it.
