For tmpdir-gcc.dg-struct-layout-1/t005 c_compat_x_tst.o-c_compat_y_tst.o on
powerpc-apple-darwin9 at -m64, the line in t005_test.h that causes the testcase
failure is...

T(998,df a;Talllong b:BQN(20);long long int c:BQN(1);TE4 d:19;long int
e;,F(998,a,140017.484375,-160009.218750)B(998,b,-303431,345440)B(998,c,0,0)B(998,d,e4_253,e4_2)F(998,e,3562377756672343063LL,5761410617366885841LL))
