Your initTools and shutDownTools declarations are OK, but they are not
necessarily the problem. Are you using any #pragma optimizes, because you
can turn the stack repair code off -- which means that ANY ints-instead-of-
longs will do you in.

also make sure you declare argc as int and argv as char ** or char *[]. Sorry
this is dumb-dumb checking but I've caught myself for things like it before.

ok, this should also be fine. I'd suggest adding the variable int sp; and the
following code just inside the enclosing brackets of main:

asm	{
	tsc
	sta	sp
	}
printf("stack pointer is $%x\n", sp);

If you see both printf's and the values are different then something is
definately wrong somewhere. You may want to try an isolate-and-test strategy
to figure out where the offending statement is -- and it might be a library
function but keep your mind open.

My sentiments exactly.
