Yeah. I think that such a thing (which works similarily to Nu-Mega's
BoundsChecker) would be a great thing. And since it'd be in the compiler
itself, it'd work seamlessly just showing the programmer stupid typos or
mistakes s/he made. I have many hours behind me spent tracking stupid
bugs which were result of just missing
a '+' here or '=' there. Take, for example, the famous bug:

	#define SOME_MACRO(x) ((x < 3) ? (x) : 0)

	char   *foo = some_ptr_to_some_string;

	while(SOME_MACRO(*foo++))
		counter++;

This code might work for some time (even a long one) without any
problems, and yet if you want to look at EVERY element of 'foo' string,
you might find yourself out in the bushes some day...
NM BoundSchecker catches this bug, and I imagine so does this checker -
it'd be great to have it aboard.

I second it. Any patches proposed must be checked thoroughly by the
people who really need and use them. We 
have checked the __attribute__((section)) patch and it works OK - it's
got its pass. Now, I heard that the
Pentium patch makes many Linux drivers go crazy - do you really want it
now, guys? I don't.

If you can, do it, please.

Hey, that's the start! I'd suggest setting up a strictly INFORMATIONAL
web page with a list of all the patches applied so that it all is, at
least a little bit, co-ordinated. Also a posting to djgpp-announce would
be desired.
