Does 'C' specify how the bit fields are arranged?
My copy of 'The ANSI C Programming Language' (by K&R) says 'Almost
everything about bit fields is implementation dependent.  ....  Fields
are assigned left to right on some machines and right to left on others.'
And in its appendix titled 'ANSI implementation-specific standards' my
Borland C++ 3.1 manual has an entry specifying 'The order of allocation
of bit fields within an int.'
