This issue may have been discussed before, but I'll ask anyway...

Does anyone know how to force the C compiler to align long words in a
structure on 16 bit boundaries?  I see there's a -misalign switch to
handle "misaligned" data, but I can't seem to force the structure elements
to align on 16-bit boundaries.  Every "long", "struct", and "union" is
forced onto a 32-bit boundary.

This is especially confusing for me, since "sizeof" is returning the
proper structure size (as if the data were in 16-bit alignment).

I can't change the structure.  I am dealing with data stored on hundreds
of tapes, and am trying to use the same #include file that our other
systems are using.

Any suggestions?
