 		 #23589 - Keil: if(x & 0x0f == 0) -> dead code
if(x & 0x0f == 0) { do something } versus if(!(x & 0x0f)) { do something }:

Maybe i have missed an ANSI C rule?? With old Keil compiler (V3.40) both versions show the same results. With new compiler versions (6/7) the first version recognizes dead code which is eliminated.
