That did the trick.

So, now I'm able to keep my custom file free of platform-dependent
settings, which are moved to the init file, like this:

  ;; Set the custom-file
  (setq custom-file "whatever")
  ;; Load the platform-independent customization
  (load custom-file)
  ;; Set the platform-specific customization
  (if (display-graphic-p)
    (if (eq system-type 'windows-nt)
        (custom-set-faces <Stuff specific to MS-Windows>)
      (custom-set-faces <Stuff specific to Other OSes>)))
  ;; Reset de state of the faces customized above, so that they
  ;; don't get written to the custom-file when some customization
  ;; is saved.
  (put 'default 'saved-face nil)
  (put 'variable-pitch 'saved-face nil)

Thanks Drew!
