Oops sorry, I did miss out that important fact didn't I?  I meant

I'll be doing some further checks tomorrow but up until now, the struct
alignment of gcc-core-3.4.4-3 seems to match MS Visual C++ when VC++
is set to 8-byte alignment (at least - it matches it more closely than when
I set VC++ to 1-byte alignment).  I'm not suggesting that either compiler
is at 'fault' in any sense;  they just do the same job slightly differently.
This is why I want to find out what happens when they're both set to
"no packing".
