	* include/bits/fstream.tcc
	(basic_filebuf::_M_allocate_internal_buffer): Remove extraneous
	try/catch blocks.
	* src/localename.cc (locale::_Impl::_M_install_facet): Same.

	* docs/html/install.html: Tweak, add bits about required locales
	for the 22_locale tests when using the gnu model.

	* testsuite/27_io/istream_sentry.cc: Tweak.

    <p>As of June 19, 2000, libstdc++ attempts to use tricky and
       space-saving features of the GNU toolchain, enabled with
-      <code>-ffunction-sections -fdata-sections -Wl,--gc-sections</code>.
-      To obtain maximum benefit from this, binutils after this date
-      should also be used (bugs were fixed with C++ exception handling
-      related to this change in libstdc++-v3).  The version of these
-      tools should be <code>2.10.90</code>, and you can get snapshots (as
-      well as releases) of binutils
-      <a href="ftp://sources.redhat.com/pub/binutils">here</a>.

+        <dd>If you are using gcc 3.1 or later on linux, and are using
+        the gnu locale model (enabled by default for sufficient
+        versions of glibc), the following locales are used and tested
+        in the libstdc++ testsuites: en_HK, en_US, fr_FR, fr_FR@euro,
+        de_DE, de_DE@euro, ja_JP.eucjp, and it_IT. Failure to have the
+        underlying "C" library locale information installed will mean
+        that C++ named locales for the above regions will not work:
+        because of this, the libstdc++ testsuite will not pass the
+        named locale tests. If this isn't an issue, don't worry about
+        it. If named locales are needed, the underlying locale
+        information must be installed. Note that rebuilding libstdc++
+        after locales are installed is not necessary.

+        <p>
+ 	  <li> install all locales

+	  <p> <code> rpm -i --define "_install_langs all" 
+	  glibc-common-2.2.5-34.i386.rpm </code> </p>
+ 	  <li> install just the necessary locales
+	  <p> <code> localedef -i de_DE -f ISO-8859-1 de_DE </code> </p>
