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.
