Move the heavy lifting from cl-seq.el to C. src/ChangeLog addition: 2010-12-30 Aidan Kehoe <kehoea@parhasard.net> Move the heavy lifting from cl-seq.el to C, finally making those functions first-class XEmacs citizens, with circularity checking, built-in support for tests other than #'eql, and as much compatibility with current Common Lisp as Paul Dietz' tests require. * fns.c (check_eq_nokey, check_eq_key, check_eql_nokey) (check_eql_key, check_equal_nokey, check_equal_key) (check_equalp_nokey, check_equalp_key, check_string_match_nokey) (check_string_match_key, check_other_nokey, check_other_key) (check_if_nokey, check_if_key, check_match_eq_key) (check_match_eql_key, check_match_equal_key) (check_match_equalp_key, check_match_other_key): New.

Dump the cl-parsing-keywords macro, but don't use defun* for the functions we define that do take keywords, dynamic scope lossage makes that not practical. * subr.el (sort, fillarray): Move these aliases here. (map-plist): #'nsublis is now built-in, but at this point #'eql isn't necessarily available as a test; use #'eq. * obsolete.el (cl-delete-duplicates): Make this available for old compiler macros and old code. (memql): Document that this is equivalent to #'member*, and worse. * cl.el (adjoin, subst): Removed. These are in C.
