Thanks to all of you that replied. Most replies seemed to point out that my
original approach was right, so I went back and poked a bit and found out
previous stack overflows had some how corrupted a couple of data files which
caused me to think the above didn't enlarge the stack.

To make sure, I called Borland too and they gave me the same answer.
So to sum it up:

To extend the size of stack, put the following line before main() and ignore
the linker warning!
	extern unsigned _stklen=nnnn; /* nnnn= required stack size. */

Thanks again to all those who replied.
