2001-02-24  Ben Elliston  <[e-mail]>

	* config.guess: Match Linux x86 systems explicitly.  Allow unknown
	architectures to fall through to the default case.

2001-02-23  Ben Elliston  <[e-mail]>

	* config.guess: More Linux cleanup. Match more in the top-level
	case statement and less by groking the output of ld.

	* config.sub: Recognise [cjt]90-*. From Kevin Ryde.

2001-02-13  David Edelsohn  <[e-mail]>

	* config.guess (ia64:AIX): New case.
	(*:AIX): Expand AIX V4 case to include V5.  Remove unnecessary `H'
	option from lsattr.  Check for string "POWER" with prepended space
	to distinguish from PowerPC_POWER3.  Use ${UNAME_VERSION} instead
	of assuming "4" to match the expanded case.

2001-02-13  Kevin Ryde  <[e-mail]>

	* config.sub: Recognise t90, c90, j90 without -cray. Preserve t90
