Oops... my apologies to zortech.  I was quite mistaken about what other
compilers do and my understanding of C.  In particular, this program:

main()
{
int a=0;
int *b= &a;
printf("%d\n", (*b) + (a++) );
}

Produces the result '1' on all compilers I've tried it on except GNU C, where
it produces the result '0'.

Most compilers assume 'a++' means "move a to tmp, increment a, use tmp for
rest of expression"

I (and I guess RMS too) thought it meant "use a for expression.  When
expresion is finished, increment a"   I think this definition is slightly
faster since with it one less register is free to use for other things in an
expression.  But K&R doesn't say which is to be used so I guess they're both
right.
