| 23 | /* The <mLib/bits.h> header defines a large number of types and macros for |
| 24 | * various kinds of bithacking. Notably, it has machinery for autodetecting |
| 25 | * suitable types holding (at least) various numbers of bits -- a service |
| 26 | * which C99 provides through other means. |
| 27 | * |
| 28 | * This file provides a small portion of the <mLib/bits.h> interface, just |
| 29 | * enough to make the pieces of code lifted from Catacomb feel at home. |
