+Subject: [PATCH] PR libstdc++/89466 avoid slow xsltproc command in configure
+
+Note: Backported from a4395a846a9343960714568e7cf8af4425e63a50.
+
+Certain broken versions of xsltproc ignore the --nonet option and will
+attempt to fetch the docbook stylesheet from the WWW when it isn't in
+the local XML catalog.
+
+This patch checks for the local stylesheet directory first, and doesn't
+use xsltproc if no local stylesheets are found. Checking for the local
+directory is done using xmlcatalog if available, only checking the
+hardcoded list of directories if xmlcatalog fails. The right directory
+for Suse is added to the hardcoded list.
+
+This should avoid doing an xsltproc check that would need to download
+the stylesheet, so no network connection is made even if a broken
+xsltproc is present.
+
+	PR libstdc++/89466
+	* acinclude.m4 (GLIBCXX_CONFIGURE_DOCBOOK): Reorder check for local
+	stylesheet directories before check for xsltproc. Try to use
+	xmlcatalog to find local stylesheet directory before trying hardcoded
+	paths. Add path used by suse to hardcoded paths. Adjust xsltproc
+	check to look for the same stylesheet as doc/Makefile.am uses. Don't
+	use xsltproc if xmlcatalog fails to find a local stylesheet.
+	* configure.ac: Check for xmlcatalog.
+	* Makefile.in: Regenerate.
+	* configure: Likewise.
+	* doc/Makefile.in: Likewise.
