extremely slow emacs+ILISP+CLISP on Win98

extremely slow emacs+ILISP+CLISP on Win98

[Michael D. Kersey]

I've installed emacs, ILISP and CLISP on a Windows 98 system according
to the instructions at the Common LISP cookbook at
http://cl-cookbook.sourceforge.net/windows.html

However when running emacs in CLISP mode, execution is excruciatingly
slow, taking seconds per key-press for syntax-checking. This on a 1.7
GHz system (512MB memory). 

Is this typical for the emacs-ILISP-CLISP combination?

Bill Clementson, the author of the URL above, kindly contacted me
directly and provided the following fix which properly addressed my
problem. My thanks to Mr. Clementson for both the original URL and for
the problem correction.
