>Description:

XPG says:

	void *sbrk(intptr_t incr);

We say:

	char *sbrk(int incr);

This isn't right. We should probably fix it.
>How-To-Repeat:

man sbrk
fgrep sbrk /usr/include/unistd.h

>Fix:

I'd just change it if we can safely do that. Unfortunately, it appears 
that the function signatures may need to alter for machines where a
pointer is different shape from an int.

HOWEVER, since it appears that we may need to clean up sbrk anyway
(since right now its set up weirdly -- I'm sending another PR on
that), we might be able to fix some of it at least.
