2005-05-12  Paul Eggert  <[e-mail]>

	Explanation for this subtle change:

	From: Paul Eggert <[e-mail]>
	To: [e-mail]
	Subject: config.guess, config.sub misdiagnose write errors
	
	config.guess and config.sub sometimes mishandle write errors to
	stdout: they either ignore the errors, or output invalid
	diagnostics when they occur.  For a simple (albeit unrealistic)
	example, on my Solaris 8 (sparc) host, the command "config.guess
	>&-" exits with status 0; it should exit with status 1, due to the
	write failure.
	
	* config.guess: Don't exit with an explicit exit code of 0.
	* config.sub: Likewise.

2005-05-12  Ben Elliston  <[e-mail]>

	* config.guess (i*86:skyos:*:*): New.
	* config.sub (case $os): Handle "-skyos*" as a valid OS.
	* testsuite/config-guess.data: Add a test case.
	* testsuite/config-sub.data: Likewise.

2005-05-12  Tim Rice  <[e-mail]>

	* config.guess: Add support for SCO OpenServer 6.

2005-05-12  Noah Misch  <[e-mail]>

	* config.guess (9000/[34678]??:HP-UX:*:*): Discard stderr of `cc
	-E -'; HP `cc' emits an error for it but still preprocesses
	standard input as expected.  Add comment.

	sysctl ((int[]) {CTL_HW, HW_MACHINE_ARCH}, 2, buffer, &bufsize, 0, 0)
	to return a negative number.
