Alas, it looks like HP C doesn't support __packed__ (not that I
care much about HP C):

 http://h21007.www2.hp.com/portal/download/files/unprot/aCxx/Online_Help/pragmas.htm#Attributes

Maybe a macro expanding to __attribute__((aligned(1))) on the fields
would work?  The same macro could expand to __declspec(align(1)) in
the MSVC build.

Thanks,
Jonathan
