[I noticed that this mail sent earlier appeared to have been redirected to a different MX than the mail.xemacs.org greylister and never retried.] If Lisp_Object is a union (not an int), then constructs such as assert (make_int (1) == mapped); /* line 2826 symbols.c */ need to be assert (EQ(make_int (1), mapped)); and Qzero != res /* line 3250 symbols.c */ need to be !EQ(Qzero, res) The changes suggested lead to a working XEmacs binary when unions are used for Lisp_Objects. I have not tested with ints used instead. The ChangeLog for the failing build 2008-08-23 Aidan Kehoe <kehoea(a)parhasard.net&gt; * eval.c (Fuser_variable_p): Moved to symbols.c * symbols.c (Fcustom_variable_p): Moved here from custom.el. (user_variable_alias_check_fun): Mapper function used in `user-variable-p'. (Fuser_variable_p): Moved here from eval.c, to allow it to examine the variable alias chain. Expanded to check each entry in the variable alias chain for signs of being a user variable; documentation updated, noting the differences between GNU's behaviour and ours (ours is a little more sensible) (map_varalias_chain): New. Given a C function, call it at least once for each symbol in a symbol's varalias chain, signalling an error if there's a cycle, and returning immediately if the function returns something other than Qzero. (Fdefvaralias): Correct the use of the word "alias" in the docstring and in the argument name. Motivate this in a comment. Add support for a DOCSTRING argument, something GNU has too, and document this * gc.c (vars_of_gc): Start the docstring of `garbage-collection-messages' with an asterisk, to indicate that it's a user variable. gcc-4.2 -c -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts -Wpacked -Wpointer-arith -Wunused-parameter -g -Os -pipe -mcpu=970 -mtune=970 -mpim-altivec -arch ppc -Demacs -I. -I/Users/royar/src/xemacs-hg/src -DHAVE_CONFIG_H -DXTHREADS -I/opt/local/include -I/usr/X11/include -I/opt/local/include/freetype2 -I/opt/local/include -I/usr/X11/include symbols.c symbols.c: In function 'Fuser_variable_p': symbols.c:2826: error: invalid operands to binary == (have 'Lisp_Object' and 'Lisp_Object') symbols.c: In function 'map_varalias_chain': symbols.c:3250: error: invalid operands to binary != (have 'Lisp_Object' and 'Lisp_Object') make[1]: *** [symbols.o] Error 1 make: *** [src] Error 2 -- Dr. Robert Delius Royar Associate Professor of English Morehead State University Morehead, Kentucky _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
