-//
-// Written by Eryk Vershen
-//
-// Bitfields are not particularly transportable between big and little
-// endian machines. Big endian machines lay out bitfields starting
-// from the most significant bit of the (one, two or four byte) number,
-// whereas little endian machines lay out bitfields starting from the
-// least signifcant bit.
-//
-// These routines were written to support some bitfields in a disk
-// data structure (partition map) whose original definition was on
-// a big-endian machine.
-//
-// They only work on 32-bit values because I didn't need 16-bit support.
-// The bits in the long word are numbered from 0 (least significant) to
-// 31 (most significant).
