K 10 svn:author V 2 dg K 8 svn:date V 27 1994-09-15T10:52:46.000000Z K 7 svn:log V 367 Brought over from 1.1.5: Fix from Bruce Evans. There were missing sets of parantheses: 1. The checks for the standard data selectors were botched, so %ss == 0 and probably %cs == 0 were allowed. A fix is enclosed. The checks for the standard selectors could be omitted without losing anything since the standard selectors pass the valid_ldt_sel() tests. END
