[Voted into WP at August, 2010 meeting.]
Proposed resolution (February, 2010):
Change 11.4.10 [class.bit] paragraph 3 as follows:
...It is implementation-defined whether a plain (neither explicitly signed nor unsigned) char, short, intor, long, or long long bit-field is signed or unsigned...
The type long long is missing from the list of bit-field types in 11.4.10 [class.bit] paragraph 3 for which the implementation can choose the signedness. This was presumably an oversight. (If that is the case, we may want to reconsider the handling of 7.3.7 [conv.prom] paragraph 3: a long long bit-field that the implementation treats as unsigned will — pending the outcome of issue 739 — still promote to signed long long, which can lead to unexpected results for bit-fields with the same number of bits as long long.)
