 def _fixup_record_bitfields_type(self, s):
 """Fix the bitfield packing issue for python ctypes, by changing the bitfield type, and respecting compiler alignement rules. This method should be called AFTER padding to have a perfect continuous layout. There is one very special case: struct bytes3 { unsigned int b1:23; // 0-23 // 1 bit padding char a2; // 24-32 }; where we would need to actually put a2 in the int32 bitfield. We also need to change the member type to the smallest type possible that can contains the number of bits. Otherwise ctypes has strange bitfield rules packing stuff to the biggest type possible. ** but at the same time, if a bitfield member is from type x, we need to respect that """
