It looks like major changes were recently merged into the gcc trunk, and I haven't had a chance to test those, so it may well be fixed.  But more importantly, so far I haven't read anything here to dissuade me that they are the right target.

The bitfield changes didn't make it into gcc-4.7; we're still working 
through implementation details.   GCC's bitfield support is a horrid 
nasty mess which has made implementation of the standard problematical. 
   It's on Aldy's plate for gcc-4.8.
