I've discovered a couple of interesting C extensions in THINK C that no
one has mentioned yet:
- #define _H_Include
in a file called Include.h will cause the compiler to search the .h only
once, as if you used the (now cliche) construct:
#ifndef _H_Include
#define _H_Include 1
... your stuff here ...
#endif
- structures can be open-ended without causing a compiler error, as in:
struct {
Rect bBox;
int sizObj;
char data[];
} object;
This is one of the few things that Pascal examples make this C programmer
envious of (the other being with..do).
Any comments?

It's certainly better than Pascal's Packed Array[0..0] of char; -- DISCLAIMER: Not only does the University not share my opinions, they don't want me sharing my opinions.
