67 * Mapping table -- please maintain in numeric sorted order with respect to
68 * the BSM constant. Today we do a linear lookup, but could switch to a
69 * binary search if it makes sense. We only ifdef errors that aren't
70 * generally available, but it does make the table a lot more ugly.
71 *
72 * XXXRW: It would be nice to have a similar ordered table mapping to BSM
73 * constant from local constant, but the order of local constants varies by
74 * OS. Really we need to build that table at compile-time but don't do that
75 * yet.

78 * support catalogues; these are only used if the OS doesn't have an error
79 * string using strerror(3).
