GnomeICU and playsound.c

[Gleef <dzol virtual-yellow com>]

In playsound.c in GnomeICU, it doesn't bother to check if sound support is
installed before including all sorts of sound-dependant files.  To make
matters more confusing, some of the sound stuff is surrounded with 
"#ifdef GNOME" conditionals, as if GNOME being defined means that there is
sound support.

Is the proper fix to nest "#ifdef SOUND" inside the "#ifdef GNOME"s,
replace them, or something completely different?

Thanks,
