    Revert #if changes
    
    I changed some "#ifdef"s to "#if defined"s by mistake, so I reverted them.
    
    * src/alloc.c: Reverted.
    (garbage_collect): Reverted.
    * src/emacs.c (main): Reverted.
    * src/image.c (xpm_load_image): Reverted.
    (image_disable_image): Reverted.
    (image_build_heuristic_mask): Reverted.
