My experience with Win98 is that both before and after the patch,
snapshots 20051229 and 20060103 12:55:23, the command
"printf '\a%1000s\a' 1" produced two tweets on the motherboard
speaker (which is rather faint to hear since I keep my box underneath
the desk), rather than playing a .wav file on my speakers which
are located on my desk. Yes, my 266MHz box is slow enough that
printing one thousand characters had enough noticeable I/O delay
that I could distinguish between the two beeps. I would much
rather hear a .wav file, though (or not hear, as the case may be,
when I mute my desktop speakers - there is no way to mute the
motherboard speaker).

I had similar results; -1 just hit the motherboard, but 0-15 gave
the default .wav that I hear from other apps, 16-31 gave the
typical error .wav, etc. In fact, changing control panel, sounds,
Windows:Default sound had an effect on the test app when called
with argument 0, and changed the contents of
/proc/registry/HKEY_CURRENT_USER/AppEvents/Schemes/Apps/.Default/.Default/.current/@.
Maybe Win9x needs to use MessageBeep(0) to play a .wav.
