Setting CPLUS_INCLUDE_PATH to include the dir containing your header
file and including the header as <header.h> make it a system header. GCC
does not warn about system headers unless you specify -Wsystem-headers 

For your original problem, why not just #undef the builtin defines
before
redefining  You don't need __GNUC__ version info for that.
