Thanks for the suggestion, although I don't really understand what's
the difference between those declarations.

Unfortunately, this still fails.


;;  test1.scm

(use srfi-13)

; (declare (uses srfi-13))

; (eval-when (compile load eval)
;   (require-extension srfi-13))

(define-macro (dc stuff)
  (string-downcase stuff))

(print (dc "ABC"))

% csc test1.scm
