definitions in macros?

Hi there,

in my quest to get lilypond working with GUILE 2+, I've hit another
stumbling block.

In order to make compilation with GUILE 2+ working, we have to move
away from runtime symbol definition (ie. module-define! calls).

In the code below, it looks like only one of the two definitions in
the body of my-macro-new takes effect. Is this expected, and if so,

(defmacro-public my-macro-old (command-and-args . definition)
  (module-define! (current-module) 'x1 "I am X1\n")
  (module-define! (current-module) 'x2 "I am X2\n"))

(defmacro-public my-macro-new (command-and-args . definition)
    `(define p "i am P\n")
    `(define q "i am Q\n"))

(my-macro-old 1 2)
(my-macro-new 1 2)
(display x1)
(display x2)
(display q)
(display p)
