Offset and Bit Mask for Bit Fields?

[Dimitry Golubovsky]

Hi,

If one wants to automatically determine offset of a regular field in a
C structure, one uses `offsetof'

According to the documentation, 

==============
This macro (offsetof) won't work if member is a bit field; you get an
error from the C compiler in that case.
==============

Do there exist any means in gcc to measure offsets (of enclosing
integer field) and bit mask for bit fields?

If not, any chance to add them in the future?
