Fewer algorithmic complexity surprises, nicer errors, mapcarX(), maplist() src/ChangeLog addition: 2010-09-01 Aidan Kehoe <kehoea@parhasard.net> * fns.c (list_merge, list_array_merge_into_list) (list_array_merge_into_array): Avoid algorithmic complexity surprises when checking for circularity in these functions. (Freduce): Fix some formatting, in passing. (mapcarX): Drop the SOME_OR_EVERY argument to this function; instead, take CALLER, a symbol reflecting the Lisp-visible function that called mapcarX(). Use CALLER with mapping_interaction_error() when sequences are modified illegally. Don't cons with #'some, #'every, not even a little. (Fmapconcat, FmapcarX, Fmapvector, Fmapcan, Fmapc, Fmap) (Fmap_into, Fsome, Fevery): Call mapcarX() with its new arguments. (Fmapcan): Don't unnecessarily complicate the nconc call. (maplist): Take CALLER, a symbol reflecting the Lisp-visible function that called maplist(), rather than having separate arguments to indicate mapl vs. mapcon. Avoid algorithmic complexity surprises when checking for circularity. In #'mapcon, check a given stretch of result for well-formedness once, which was not previously the case, despite what the comments said. (Fmaplist, Fmapl, Fmapcon): Call maplist() with its new arguments.

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.
