Hi Clarence,

Nicolas already said it all, nealry. I'd just like to add:

With QDataStream, it *will* be portable. Others will help testing it...there 
are quie a few people using Sparc (which will debug endianness) and Alpha 
(which will catch most alignment issues by default).

Luckily for us, MS had to make this stuff work on Macs. Since the 68k is 
bigendian and requies natural alignment, MS have solved this problem "de 
jure" in their specs provided you simply use a little endian QDatastream.

The Excel and Powerpoint filters have good examples of this stuff (as does wmf 
and msod too).

Thanks, Shaheed
