structure has #pragma pack(8) in Windows SDK (AMD64) and #pragma pack(1) in wine headers

[Ilya Basin]

The struct in question is CSFV defined in shlobh.h. If I try to
compile shell32_test for x64 using headers from windows 2008 SDK, I
get assertion failure here:
http://source.winehq.org/source/dlls/shell32/tests/generated.c?v=wine-1.2-rc...

Is it normal for wine to have different structure packing?
