A tentative fix for SF bug #503837 (Roeland Rengelink): type.__module__ problems (again?) This simply initializes the __module__ local in a class statement from the __name__ global. I'm not 100% sure that this is the correct fix, although it usually does the right thing. The problem is that if the class statement executes in a custom namespace, the __name__ global may be taken from __builtins__, in which case it would have the value __builtin__, or it may not exist at all (if the custom namespace also has a custom __builtins__), in which case the class statement will fail. Nevertheless, unless someone finds a better solution, this is a 2.2.1 bugfix too.

/* A perhaps slow but I hope correct implementation of memmove */

extern char *memcpy(char *, char *, int);

char *
memmove(char *dst, char *src, int n)
{
	char *realdst = dst;
	if (n <= 0)
		return dst;
	if (src >= dst+n || dst >= src+n)
		return memcpy(dst, src, n);
	if (src > dst) {
		while (--n >= 0)
			*dst++ = *src++;
	}
	else if (src < dst) {
		src += n;
		dst += n;
		while (--n >= 0)
			*--dst = *--src;
	}
	return realdst;
}
