gcc43-pr33984.patch
I've tried to fix this by the attached patch.
standard_conversion also uses is_bitfield_expr_with_lowered_type, but
reference_binding was not. Additionally, I've noticed that the 2006 change in
layout_class_type dropped all qualifiers from the bitfield's type if
c_build_bitfield_integer_type needs to be used.
Unfortunately this causes a regression on g++.old-deja/g++.robertl/eb5.C
- to type in this case is also the lowered bitfield type, so it fails.
Mark, any ideas?
