 experimenting to figure out how to stop gcc 5.3.0 from warning with
 -Wconversion. This version gets a warning:

+  #define SETBIT(a,b) a[(b)/8] |= (uint8_t)(1u << ((b)&7))
 
 Let's hope the apparently less efficient version isn't actually so bad if the
 compiler is clever with identical subexpressions. */
