>Environment:	all platforms

>Description:
	The xntp-3.5.90 distribution supports many more clocks than are
	currently compiled into an xntpd on NetBSD from sources generated
	by xntp2netbsd. This is probably a workaround for two small bugs
	in the xntp source which I have appended a fix for. The addition of
	the refclocks in question has afterwards triggered bugs in the 
	conversion script itself, resulting in invalid Makefiles and
	non-working reference clocks. Appended is a patch for both,
	the configuration changes and the bug fixes.
>How-To-Repeat:
	N/A unless you have one of the affected refclocks
>Fix:
	first, the fixes to the xntp-current distribution.
	"Cc:" Frank and Harlan: I have commited these to the Erlangen
		repository, FYI.

	(The last Hunk reflects the fact that we on NetBSD still lose
	when it comes to SIGIO because no-one bothered to implement FSETOWN,
	see kern_descrip.c, line 250 and sys_generic.c, line 477:
	FSETOWN is very different from settpgrp ! But that is another
	problem that is already filed, I think)
