+<para><userinput>--enable-clocale=gnu:</userinput> There is a risk that
+some people will build ABI incompatible C++ libraries if they didn't install
+all the glibc localedata. Using --enable-clocale=gnu ensures that the "right
+thing" is done in all cases. If you don't want to use this option and don't
+want to build all the locales, then at least make sure you installed the
+<emphasis>de_DE</emphasis> locale with Glibc, since that's the specific locale
+GCC will check for to determine which locale mode to use (if de_DE is
+found, <emphasis>gnu</emphasis> mode is used, which is the corrent one to
+use).</para>
