--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- This bug report is for C++, where bit-field width is explicitly not part of the type and bit-field types wider than int are not extensions, not for C, where there is a line of C90 DRs treating the width as part of the type and things that are not defined at all if it is not part of the type. The C++ front end should already convert bit-fields to their declared types when needed (convert_bitfield_to_declared_type). So I don't agree with the stated rationale for closure.
