Then I misunderstood what you meant by "rc file". I assumed
you meant one's own personal "run control" (which is what "rc"
stands for) file in one's home directory, such as "~/.cmucl-init"
is for CMUCL. I can understand not wanting to have to have every user
needing to modify their personal init file just to get scripting.

The "site-switch-script.lisp" file mentioned above, by contrast,
goes in the system library directory, not anyone's home directory,
and thus should be considered an "optional module" installed with
the software. It includes a tweak to the "site-init.lisp" file that
is already there [to grab early control, so that the script's options
(if any) don't get interpreted as CMUCL command-line options]. As such,
it gives the ability to do "#!" scripting to *all* users of CMUCL on
the system, not just one.

If you don't like to do it that way, then just hack the same
thing into the "site-init.lisp" file. Or into the source of CMUCL
itself and recompile. The place to do the latter is in the file
".../src/code/save.lisp", in the function SAVE-LISP, in the LABELS
((%RESTART-LISP ...)), just after the (LOAD SITE-INIT ...) call.
In any case, you need to do it *before* the first call to FIND-SWITCH,
otherwise things can get all messed up if the user types the wrong
thing as command-line args to one of his/her scripts.
