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.

To use: You need to build and install the XEmacs distribution. Also you need the xemacs packages in both source and installed versions. Edit "dirs.py" to reflect the locations of the above components. Edit "version.py" to reflect the current version, as well as the welcome message. Run python pre_wise.py > xemacs-XXX.wse (for XXX use a version or date code of your choosing) Run cmd /c xemacs-XXX.wse to produce xemacs-XXX.exe "pre_wise.py" is a preprocessor for the Wise installer maker. It reads "xemacs.tmpl" which is a Wise input file, except that certain portions are enclosed in triple angle brackets <<<like this>>> These portions are evaluated as Python expressions and replaced by the string representations of the resulting value. This allows for things to change from release to release without having to re-do the Wise installation each time. Also it keeps you from having to manually drag-n-drop all the package files, which is rather tedious!
