--- Comment #9 from npl at chello dot at ---
I am using gcc 6.1 and I have the same problem with disabling -Wpsabi


echo '#pragma GCC diagnostic ignored "-Wpsabi"' >test.c
gcc -c test.c


test.c:1:32: warning: '-Wpsabi' is not an option that controls warnings
[-Wpragmas]
 #pragma GCC diagnostic ignored "-Wpsabi"
