I can't find anything to indicate that data structures are always 16-byte
aligned.  Even if they are, if it's not documented as the way the compiler
assigns memory, then it is subject to change without notice.  I'd hate to
have a program start blowing up with pointer errors just because I
recompiled it after installing a new release or even just applying PTFs.

The ALIGN keyword insures that float, signed, and unsigned integers are
aligned on the appropriate boundaries (2-byte, 4-byte, and 8-byte) for the
best performance.  This is not going to insure that a 16-byte CHARACTER
field being used for a pointer is aligned on a 16-byte boundary.
