From: Stefan Weil <s...@weilnetz.de> 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.
