6975899Sjoe * the BSM constant.  Today we do a linear lookup, but could switch to a
7075899Sjoe * binary search if it makes sense.  We only ifdef errors that aren't

7375899Sjoe * XXXRW: It would be nice to have a similar ordered table mapping to BSM
7475899Sjoe * constant from local constant, but the order of local constants varies by
7575899Sjoe * OS.  Really we need to build that table at compile-time but don't do that
7675899Sjoe * yet.

7875899Sjoe * XXXRW: We currently embed English-language error strings here, but should
7975899Sjoe * support catalogues; these are only used if the OS doesn't have an error
