Your email client has corrupted this patch, changing TAB characters
into sequences of spaces.

Also, you should not just have a macro expanding to two statements,
because now things like:

	if (x)

doesn't do what you intended.

Either make this an inline function, or enclose the two readl()
statements inside of a "do { } while (0)"
