The function load-help and the X11 support function make-fake-menu-bar are no longer generally available. Their symbols are internal to the XLISP package.
The assignment of internal symbols to packages is likely to change in the near future and should not be relied upon.
The functions get-lambda-expression , num-to-string , and strcat have been removed since similar Common Lisp functions are available. You should use function-lambda-expression , prin1-to-string and concatenate instead.
