My compiler gave Beppe's error message when I modified my program like this:

void funct(char *dest, const char *srce, const size_t count)
{                                                           
  while(count-- != 0)                                       
  {                                                         
    *dest++ = 256 - (*srce++) ;                             
  }                                                         
}                                                           

Don't you think, that as the calling function is declared as static, and count 
variable is defined there, compiler did some wrong assumptions?
