can anyone find this in the ANSI C standard

I am not asking what it will do, that is a simple experimnt that I can do myself. Does anyone have specific knowledge of whether the following for loop where WFLcnt is an unsigned char is specified in the ANSI C standard to run 0 or 256 times.

  for ( WFLcnt = 0 ; WFLcnt !=0 ; WFLcnt++)
  {
   .....
  }
