-# Configuration subroutine to validate and canonicalize a configuration type.
-# Supply the specified configuration type as an argument.
-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-# This file is supposed to be the same for all GNU packages

-# Each package is responsible for reporting which valid configurations

-# a failure to support a valid configuration from a meaningless
-# configuration.

-# The goal of this file is to map all the various variations of a given

-# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

-**
-** Do shell-style pattern matching for ?, \, [], and * characters.
-** Might not be robust in face of malformed patterns; e.g., "foo[a-"
-** could cause a segmentation violation. It is 8bit clean.
-**
-** Written by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
-** Rich $alz is now <rsalz@osf.org>.
-** April, 1991: Replaced mutually-recursive calls with in-line code
-** for the star character.
-**
-** Special thanks to Lars Mathiesen <thorinn@diku.dk> for the ABORT code.
-** This can greatly speed up failing wildcard patterns. For example:
-** pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-*
-** text 1: -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
-** text 2: -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1
-** Text 1 matches with 51 calls, while text 2 fails with 54 calls. Without
-** the ABORT code, it takes 22310 calls to fail. Ugh. The following
-** explanation is from Lars:
-** The precondition that must be fulfilled is that DoMatch will consume
-** at least one character in text. This is true if *p is neither '*' nor
-** '\0'.) The last return has ABORT instead of FALSE to avoid quadratic
-** behaviour in cases like pattern "*a*b*c*d" with text "abcxxxxx". With
-** FALSE, each star-loop has to run to the end of the text; with ABORT
-** only the last one does.
-**
-** Once the control of one instance of DoMatch enters the star-loop, that
-** instance will return either TRUE or ABORT, and any calling instance
-** will therefore return immediately after (without calling recursively
-** again). In effect, only one star-loop is ever active. It would be
-** possible to modify the code to maintain this context explicitly,
-** eliminating all recursive calls at the cost of some complication and
-** loss of clarity (and the ABORT stuff seems to be unclear enough by
-** itself). I think it would be unwise to try to get this into a
-** released version unless you have a good test data base to try it out
-** on.

+** Do shell-style pattern matching for ?, \, [], and * characters.

+**
+** Written by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
+** Rich $alz is now <rsalz@osf.org>.
+** April, 1991: Replaced mutually-recursive calls with in-line code
+** for the star character.
+**
+** Special thanks to Lars Mathiesen <thorinn@diku.dk> for the ABORT code.
+** This can greatly speed up failing wildcard patterns. For example:
+** pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-*
+** text 1: -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
+** text 2: -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1
+** Text 1 matches with 51 calls, while text 2 fails with 54 calls. Without
+** the ABORT code, it takes 22310 calls to fail. Ugh. The following
+** explanation is from Lars:
+** The precondition that must be fulfilled is that DoMatch will consume
+** at least one character in text. This is true if *p is neither '*' nor
+** '\0'.) The last return has ABORT instead of FALSE to avoid quadratic
+** behaviour in cases like pattern "*a*b*c*d" with text "abcxxxxx". With
+** FALSE, each star-loop has to run to the end of the text; with ABORT
+** only the last one does.
+**
+** Once the control of one instance of DoMatch enters the star-loop, that
+** instance will return either TRUE or ABORT, and any calling instance
+** will therefore return immediately after (without calling recursively
+** again). In effect, only one star-loop is ever active. It would be
+** possible to modify the code to maintain this context explicitly,
+** eliminating all recursive calls at the cost of some complication and
+** loss of clarity (and the ABORT stuff seems to be unclear enough by
+** itself). I think it would be unwise to try to get this into a
+** released version unless you have a good test data base to try it out
+** on.
