Dear All,
	I know there is a newer version out there, but at the moment
that just crashes my code even more. At the moment I have some serious 
problems with the compiler. Now what I would like you to tell me is,
does DJGPP have problems with large functions? I have one function,
and inside there is a switch() statement. Now some of the cases inside
that statement cause General Protection Faults. Now I would blame
it on my code if it was not for:
	
	a) The code has been working for > 6 months

	b) Why the hell would the line 

		AdjustPalette=1;

	   Causes a protection fault. (Adjust palette is a global I'm
	   affraid).

Now, the problem only occurs currently when I set -m486 and -O3.
However, it did do it on normal compilation and I had to cut out
a function call to get it to work again. So what could be upsetting the
compiler. I can think of two possibles,

	1) It does not like large functions. Solution, I break it up,
	slowing down my main game loop, and still worrying about the
	thing falling over.

	2) The switch statement is too large. Solution a break it up,
	   making the code (bad because it is already large) look 
	   worse.

Does anybody know what I am doing to upset the compiler? I have a 
problem that I cannot send source to people in general as it is
a commercial game. 

Thanks for your time,

Nigel Hughes
