Co-operate with the byte-optimizer in the bytecomp.el labels implementation.
lisp/ChangeLog addition:
2012-05-05 Aidan Kehoe <kehoea@parhasard.net>
Co-operate with the byte-optimizer in the bytecomp.el labels
implementation, don't work against it.
* byte-optimize.el:
* byte-optimize.el (byte-compile-inline-expand):
Call #'byte-compile-unfold-lambda explicitly here, don't assume
that the byte-optimizer will do it.
* byte-optimize.el (byte-compile-unfold-lambda):
Call #'byte-optimize-body on the body, don't just mapcar
#'byte-optimize-form along it.
* byte-optimize.el (byte-optimize-lambda): New. Optimize a lambda
form.
* byte-optimize.el (byte-optimize-form-code-walker):
Descend lambda expressions, defun, and defmacro, relevant for
lexically-oriented operators like #'labels.
* byte-optimize.el (byte-optimize-body): Only return a non-eq
object if we've actually optimized something
* bytecomp.el (byte-compile-initial-macro-environment):
In the labels implementation, work with the byte optimizer, not
against it; warn when labels are defined but not used,
automatically inline labels that are used only once.
* bytecomp.el (byte-recompile-directory):
No need to wrap #'byte-compile-report-error in a lambda with
#'call-with-condition-handler here.
* bytecomp.el (byte-compile-form):
Don't inline compiled-function objects, they're probably labels.
* bytecomp.el (byte-compile-funcall):
No longer inline lambdas, trust the byte optimizer to have done it
properly, even for labels.
* cl-extra.el (cl-macroexpand-all):
Treat labels established by the byte compiler distinctly from
those established by cl-macs.el.
* cl-macs.el (cl-do-proclaim):
Treat labels established by the byte compiler distinctly from
those established by cl-macs.el.
* gui.el (make-gui-button):
When referring to the #'gui-button-action label, quote it using
function, otherwise there's a warning from the byte compiler.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with XEmacs. If not, see <http://www.gnu.org/licenses/>. This directory contains a number of XEmacs dynamic modules. These modules can be loaded directly with the command 'M-x load-module'. However, the preferred method of loading a module is to issue a "(require 'module-name)" command to the Lisp interpreter. This will store information so that a later "(unload-feature 'module-name)" can succeed. To compile one of these modules, simply enter the desired directory, type 'configure', and then 'make'. If you are building the module for an installed XEmacs, then 'make install' will place the module in the appropriate directory for XEmacs to find it later (assuming you have permission to write to that directory). A subsequent 'load-module' or 'require' will then load the module, as described above. Each of these demonstrates different features and limitations of the XEmacs module loading technology. For a complete discussion on XEmacs dynamic modules, please consult the XEmacs Module Writers Guide, which can be found in the ../info directory. For those wanting to get started with module writing, please see the 'sample' directory. It contains two subdirectories: internal and external. The 'internal' subdirectory contains the framework needed to migrate some core piece of XEmacs functionality into code that can either be compiled into the core or built as a separate module. The 'external' subdirectory contains the somewhat simpler framework needed to build a module separately from XEmacs. These should be considered starting places for module writing.
