Ah, that is why! Thanks a lot!

Now another question:
I'm in fact using `find-files' inside a function, say `find-files-ex', that
is declared in the same file and used in the `define-runtime-path-list'
The problem is that this function must be available both at compile time and
at runtime because of `define-runtime-path-list'.

I did not find anything that could do that as is, so I made this macro:

(define-syntax-rule (define-also-for-syntax head body ...)
    (define-for-syntax head body ...)
    (define head body ...)

to avoid duplication of the function code.
But I feel like it may not be the right thing to do. Am I missing something?
