Except that there's no *guarantee* that the other compilers will barf;
they are quite welcome to have a '__sizeof__' which returns what they
expect.

Anyway, if you want that, you can do it now;
	#define sizeof(x) ((int) sizeof(x))
should do what you want sizeof() to do...  (and is as safe as anything
like that can be said to be.)

That's the traditional solution.
