Unfortunately
	#define StrEq(a,b) (*(a)==*(b) && strcmp((a)+1,(b)+1)==0)
is in general incorrect: *a can equal *b and they can both be NUL
bytes, unless you know for certain that one argument will always be a
(preferably constant) non-empty string.  A correct version is
	#define STREQ(a,b) (*(a)==*(b) && strcmp((a),(b))==0)
