#ifndef fake_mLib_bits_h
#define fake_mLib_bits_h

/* The <mLib/bits.h> header defines a large number of types and macros for
 * various kinds of bithacking.  Notably, it has machinery for autodetecting
 * suitable types holding (at least) various numbers of bits -- a service
 * which C99 provides through other means.
 *
 * This file provides a small portion of the <mLib/bits.h> interface, just
 * enough to make the pieces of code lifted from Catacomb feel at home.
