The ALIGN directive for MASM may not work properly. It aligns values 2
bytes beyond where they should be aligned, e.g. if ALIGN 4 is being
used, values align only at the following offsets:

    02h, 06h, 0Ah, 0Eh, ... etc.

If ALIGN 16 (decimal) is being used, values are aligned only at the
following offsets:

    02h, 12h, 22h, 32h, ... etc.

This is not a problem for word alignment. ALIGN 2 has the same effect as
the EVEN directive.

Microsoft is researching this problem and will post new information as
it becomes available.
