as follows:

SDL -> Win32 wave mapper -> ALSA -> OSS -> Win32 Beep() -> unix_beep()

Issues are as follows:
SDL requires SDL.dll/libSDL.so
Win32 wave mapper has a larget (~ .5 sec) delay between beeps on at least
Windows 2000 (possibly 9x and NT too)
ALSA Is completely untested.
OSS works fine (best tested)  ;-)
Beep() repeatedly plays the default beep wave on 9x.
unix_beep() is succeptable to various permissions problems.

local CFLAGS.

Probobly everything with a main function will now need to be recompiled...
hopefully, auto-dependencies will fix this (touching gen_defs.h should make
the entire universe rebuild imho)

xpdev.  Essentially, sdlfuncts and the *[Mm]ain* files will become part
of xpdev.

so all you need to do is fill the wave data and break the silence loop.

while device is open and no data is playing.

Win32

device open in between then (hopefully squashing the delay on Win2k)

semaphore (and get playnote_thread to terminate).

Bug-fix in cterm_end() - use listSemPost() to signal list semaphore (and get
playnote_thread to terminate).
