Improve the implementation, documentation of #'labels, #'flet. lisp/ChangeLog addition: 2011-09-07 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el: * bytecomp.el (for-effect): Move this earlier in the file, it's referenced in byte-compile-initial-macro-environment. * bytecomp.el (byte-compile-initial-macro-environment): In the byte-compile-macro-environment definition for #'labels, put off the compiling the lambda bodies until the point where the rest of the form is being compiled, allowing the lambda bodies to access appropriate values for byte-compile-bound-variables, and reducing excessive warning about free variables. Add a byte-compile-macro-environment definition for #'flet. This modifies byte-compile-function-environment appropriately, and warns about bindings of functions that have macro definitions in the current environment, about functions that have byte codes, and about functions that have byte-compile methods (which may not do what the user wants at runtime). * bytecomp.el (byte-compile-funcall): If FUNCTION is constant, call #'byte-compile-callargs-warn if that's appropriate, giving warnings about problems with calling functions bound with #'labels. * cl-macs.el: * cl-macs.el (flet): Mention the main difference from Common Lisp, that the bindings are dynamic, not lexical. Counsel the use of #'labels, not #'flet, for this and other reasons. Explain the limited single use case for #'flet. Cross-reference to bytecomp.el in a comment. * cl-macs.el (labels): Go into detail on which functions may be called from where. Explain how to access the function definition of a label within FORM. Add a comment cross-referencing to bytecomp.el. man/ChangeLog addition: 2011-09-07 Aidan Kehoe <kehoea@parhasard.net> * cl.texi (Function Bindings): Move #'labels first, describe it in more detail, explaining that it is to be preferred over #'flet, and explaining why. Explain that dynamic bindings with #'flet will also not work when functions are accessed through their bytecodes.

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.
