Following up Toomey's and Davidson's notes
(didn't see Garcia's):
It does appear that the early-distributed v7 didn't
require = in initializers. A slightly later version
of the original 11 C compiler did; the lines Davidson quoted,
if (o!=ASSIGN)
peeksym = o;
were replaced by
if (o!=ASSIGN) {
error("Declaration syntax");
peeksym = o;
}
bringing it into conformity with K&R1, which
did require the =.
Incidentally, if anyone wants to try the v7 crypt(3),
the 'encrypt' routine has an implicit, and unwarranted,
assumption that the L and R arrays are adjacent in storage
and thus that L can be oversubscripted to access R.
This was fixed at some (surprisingly late) point too.
