Don't cons with #'mapcar calls where the result is discarded,
decide on mapc-internal at compile time if the Common Lisp functionality is
not being used.
2009-10-12 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (mapc):
New compiler macro, use mapc-internal at
compile time if we're not using the Common Lisp functionality.
* bytecomp.el (byte-compile-mapcar, byte-compile-maplist): New.
If the return value of mapcar is being discarded, compile it to a
mapc-internal call instead, and warn, because the programmer
probably can't rely on always being compiled by an XEmacs that
does this. Similarly for maplist and mapl; and use
byte-compile-funarg for map, mapl, mapcan, mapcon.

This directory contains C header files containing machine-specific definitions. Each file describes a particular machine. The emacs configuration script edits ../config.h to include the appropriate one of these files, and then each emacs source file includes config.h. template.h is a generic template for machine descriptions; it describes the parameters a machine file can specify. General XEmacs Changes ---------------------- 1. Removed all code dealing with VALBITS and XSET*. These are handled differently in XEmacs. 2. Removed all defines of WORDS_BIGENDIAN. Now determined by configure. 3. Put #ifndef PURESIZE around all PURESIZE defines so that it can be overridden at configure time. 4. Removed all defines of NO_ARG_ARRAY. The arg-array hack is not done in XEmacs. (If you want to put it back, use configure -- autoconf has a check for this.) 5. Removed all defines of BITS_PER_INT, BITS_PER_LONG -- now determined by configure. See ../s/README for a list of other changes made to the FSF 19.30 configuration files for XEmacs.
