Versions before gcc-4.6 don't support unnamed fields in initializers
(see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676).
Offset and OffsetHigh belong to an unnamed struct which is part of an
unnamed union. Therefore the original code does not work with older
versions of gcc.
Signed-off-by: Stefan Weil <sw@weilnetz.de>

This patch is needed for Debian's amd64-mingw32msvc-gcc-4.4.4
which I use for MinGW-w64 cross compilation.
Regards
Stefan W.
