I think that this need not be complicated at all.
As a matter of fact, you can do it completely legally now,
without adding any functions to Exec.library.

new * realloc(old *,newsize,oldsize)
{
	Forbid();
	FreeMem(old,oldsize);
	error=AllocAbs(newsize,old);
	if(error==0) {
		AllocAbs(oldsize,old); /* should not fail, I think :-) */
		error=AllocMem(newsize,attributes);
		if(error==0) {
			Permit();
			return(0);
		}
		Permit();
		CopyMemQuick(bla bla);
		FreeMem(old,oldsize);
		return(error);
	}
	Permit();
	return(old);
}

I have *NOT* tested this, and have only just now thought of it.
It should should work though.
