Conditionalise the old-* functions and byte codes at compile time. src/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * config.h.in (SUPPORT_CONFOUNDING_FUNCTIONS): New #define, equivalent NEED_TO_HANDLE_21_4_CODE by default, describing whether this XEmacs should support the old-eq, old-equal and related functions and byte codes. * bytecode.c (UNUSED): Only interpret old-eq, old-equal, old-memq if SUPPORT_CONFOUNDING_FUNCTIONS is defined. * data.c: Move Fold_eq to fns.c with the rest of the Fold_* functions. * fns.c: * fns.c (Fmemq): * fns.c (memq_no_quit): * fns.c (assoc_no_quit): * fns.c (Frassq): * fns.c (Fequal): * fns.c (Fold_equal): * fns.c (syms_of_fns): Group old-eq, old-equal, old-memq etc together, surround them with #ifdef SUPPORT_CONFOUNDING_FUNCTIONS. lisp/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el: Don't generate the old-eq, old-memq, old-equal bytecodes any more, but keep the information about them around for the sake of the disassembler. man/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * lispref/objects.texi (Character Type): * lispref/objects.texi (Equality Predicates): No longer document `old-eq', `old-equal', they haven't been used in years. tests/ChangeLog addition: 2011-03-17 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Only test the various old-* function if old-eq is bound and a subr.
