	* config.guess: Remove stale libc1 tests on PowerPC Linux.

2001-06-29  John Wolfe  <[e-mail]>

	* config.guess: Correct UnixWare 7 and Open UNIX 8.0 change;
	test for i586 must be a string that ends with "Pentium".

2001-06-28  Ben Elliston  <[e-mail]>

	* config.guess: On Alpha Linux, use /proc/cpuinfo to determine
	the CPU model, rather than assembling a small test program.

2001-06-27  Ben Elliston  <[e-mail]>

	* config.guess: Do not unconditionally run the script fragment
	to set $CC_FOR_BUILD. Put the script in the shell variable
	$set_cc_for_build and only evaluate it before $CC_FOR_BUILD is
	referenced. (Poor man's function inlining!)

	In future, the goal will be to reduce the dependence on a C
	compiler to detect system types by utilising other means.

2001-06-26  Ben Elliston  <[e-mail]>

	* config.guess: On MIPS Linux, use /proc/cpuinfo to determine
	the endian mode of the CPU, rather than compiling and running
	a small C program.

	* config.guess: Standardize triplet for UnixWare 7 and Open
	UNIX 8.0, improve processor detection and maintain "sysv5"

2001-06-08  Christopher Faylor  <[e-mail]>

	* config.sub: Add support for Sun Chorus.

2001-06-05  Tomislav Greguric  <[e-mail]>

	* config.guess: Add 2001 to copyright notice issued for -v.

2001-06-01  Ben Elliston  <[e-mail]>

	* config.guess (i*86:Linux:*:*): Examine the list of supported
	targets, not the list of supported emulations when capturing
	the output of "ld --help".  This causes problems on systems
	where GNU ld is built with support for all targets. Adjust
	cases in the switch accordingly.

	* config.guess: Other small Linux cleanups. Remove unnecessary
	logic for setting $VENDOR, since UNAME_MACHINE will always be
	i*86 in this case.

	machine name (eg. mn10300-unknown-elf).

2001-03-19  Philip Blundell  <[e-mail]>

	* config.sub: Allow tic80 as machine type.  Allow company name for
	h8500 and pj targets; add `unknown' component when canonicalising
	h8500-*, pj-* and pjl-*.

	* config.guess: Detect Linux on SPARC64.
