When I started using C in 1989 they were still quite common to be
seen in code I was looking at but that dropped significantly during
the following decade and I hardly ever have seen code using them
written in this millenium. So my very personal guess is that most
people use the "new" form since at least about 1995. But then I did
programming nearly exclussively under UNIX, things might be diffe-
rent for platforms were "modern" compilers weren't available that
easily. And, of course, people having to cater for the very smal-
lest common denominator (i.e. systems were no C89 compliant com-
piler exists) still have to use them in one form or another (as
the example Kaz came up with might be an example for).
If this is for the emacs C mode then, since the standard still
requires support for the "old way" (even though it might be de-
clared as obsolete) I would think it prudent not to throw it
out completely.
Regards, Jens
