jonathon, it was also the EQUALS and EQUALSN macros that failed on the
3b1.  they used to say

#define EQUALS(a,b) a && b && strcmp(a, b) == 0

(with a little embellishment, i.e., a profusion of parentheses.)

the 3b1, er 7300, er now what was it called ... oh yes, the safari-4
(this was ca. '84) would merrily generate bad code for this, dumping
core when reached.  changing the macro to

#define EQUALS(a,b) a != 0 && b != 0 && strcmp(a, b) == 0

cured the disease.  same with EQUALSN, m.m.
