 Under Windows, interrupting (with C-c C-b) doesn't work.  Emacs sends
 a SIGINT signal, but the signal is either ignored or CLISP exits
 immediately.
 
+On Windows, CLISP may refuse to parse filenames like
+"C:\\DOCUME~1\\johndoe\\LOCALS~1\\Temp\\slime.1424" when we actually

 Function arguments and local variables aren't displayed properly in
 the backtrace.  Changes to CLISP's C code are needed to fix this
 problem.  Interpreted code is usually easer to debug.
