:>It is not a good idea to use #define where you mean typedef.
:>Think about the difference between:
:>
:>typedef int *INT_PTR;
:>INT_PTR a, b;
:>
:>and
:>
:>#define INT_PTR int *
:>INT_PTR a, b;

IRRELEVANT!!!
So what that "#define INTPTR int *" doesn't work?  The original author never
claimed it did!  "#define int16 int" works fine!

In fact, 4.2bsd stdio.h contains "#define FILE struct _iobuf" (and so
do many other stdio.h's, I believe).
