Changes since 1.2: +1 -1 lines 

update for pdisk 0.8a2, from NetBSD, retaining our local changes;
summing it up:

- Clean up sources - fix naming, delete old email addresses
- Added support for display of Mac volume names
- Fix block 0 display to show logical offset of drivers
- Require confirmation of quit without write
- Fix iteration to not complain about missing devices
- Warn when creating/writing a map with more than 15 entries

and, most important, add do_update_dpme() which allows us to partition
OpenBSD slices without previous MacOS setup.

Tested with shared MacOS install on macppc, procedure there remains the
same.

// bitfield.h - extract and set bit fields
//
// 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).
