The -mms-bitfields option seems to trigger the wrong behaviour. As pointed out
by http://gcc.gnu.org/gcc-4.7/changes.html it is enabled by default since
4.7.0, and using -mms-bitfields when compiling with TDM-GCC 4.6.1 also causes
the wrong behaviour.

In contrast, compiling with -mno-ms-bitfields makes the example programs work
as expected under gcc 4.7.0.
