bug#17445: 24.4.50; defcustom doesn't define an eieio object variable on compilation

[Vitalie Spinu]

Hi,

Put the following into a new file and M-x byte-compile-file:

   (require 'eieio)
   
   (defclass A (eieio-instance-inheritor)
     ((a
       :initform 23
       :type number)))
   
   (defcustom test1  (A "aaa")
     "blabla")


Then check test1, it is not defined. As if that defcustom is invisible
to byte-compiler.  Same issue in 24.3.1.

I cannot push my package to MELPA because of this. Would really
appreciate some quick workaround.

Thanks,

   Vitalie
