Re: [Bug: 21.5-b16] (setq lookup-syntax-properties nil)... bad news

Before I evaluated it I verified that lookup-syntax-properties was t. When I am in non-vanilla XEmacs and load emacs.c and scroll around (even though lookup-syntax-properties is nil), the program has not crashed. I think that is odd. I would be glad to provide my startup file including customizations. I am still using the bad ancient technique of storing all startup setting including customs in one file which I load using an alias which points to this file: #!/bin/sh /Users/royar/usr/local/bin/xemacs -user-init-file /Users/royar/xemacs-xwin.el -geometry +50+0& I run with debug and error checking off unless I find a problem, and then I recompile. I also use union type (and know all these settings are evil decisions on my part, but they have worked well for me). here is what my describe-installation tells: uname -a: Darwin grendal.frinabulax.org 7.0.0 Darwin Kernel Version 7.0.0: Wed Sep 24 15:48:39 PDT 2003; root:xnu/xnu-517.obj~1/RELEASE_PPC Power Macintosh powerpc ./configure '--with-mule' '--with-widgets=athena' '--with-athena=3d' '--with-dialogs=athena' '--error-checking=none' '--debug=no' '--package-path=/Users/royar/usr/local/xemacs/xemacs-packages' '--cflags-warning=${CWARNINGS}' '--prefix=/Users/royar/usr/local' '--with-prefix' '--cflags=-no-cpp-precomp' '--pdump' '--with-ldap=no' '--use-union-type' '--with-xmu' '--with-xim=xlib' '--with-sound=esd' '--with-xfs' XEmacs 21.5-b16 "celeriac" (+CVS-20031025) configured for `powerpc-apple-darwin7.0.0'.
