93 * "Bitfields are great and easy to read, but unfortunately the C language
94 * does not specify the layout of bitfields in memory, which means they are
95 * essentially useless for dealing with packed data in on-disk formats or
96 * binary wire protocols." (Or ACPI tables and buffers.) "If you ask me,
97 * this decision was a design error in C. Ritchie could have picked an order
98 * and stuck with it." Norman Ramsey.
