-If you install a shared libstdc++ and, when you link a non-trivial C++
-program (for example, @file{gcc/testsuite/g++.other/delete3.C}),
-the linker reports a couple of errors about multiply-defined symbols
-(for example, @code{nothrow}, @code{__throw} and
-@code{terminate(void)}), you've probably got a linker bug, for
-which there's no known fix.  The officially recommended work-around is
-to remove the shared libstdc++.
-
-An alternative solution is to arrange that all symbols from
-@code{libgcc} get copied to the shared @code{libstdc++};
-see detailed solution below.  (Surprising as it may seem, this does
-indeed fix the problem!)  @emph{Beware} that this may bring you
-binary-compatibility problems in the future, if you don't use the same
-work-around next time you build @code{libstdc++}: if programs
-start to depend on @code{libstdc++} to provide symbols that used
-to be only in @code{libgcc}, you must arrange that
-@code{libstdc++} keeps providing them, otherwise the programs
-will have to be relinked.
-
-The magic spell is to add @option{-Wl,-all,-lgcc,-none} to the
-definition of macro @code{SHDEPS} in
-@file{libstdc++/config/dec-osf.ml} @emph{before}
-@file{alpha*-dec-osf*/libstdc++/Makefile} is created (a 
-@uref{dec-osf-shlibstdc++.patch,,patch} 
-that does just that is available).  If the Makefile already exists, run
-@file{./config.status} within directory
-@file{alpha*-dec-osf*/libstdc++} (and
-@file{alpha*-dec-osf*/ieee/libstdc++}, if it also exists).
-Remove any existing @file{libstdc++.so*} from such directories,
-and run @samp{make all-target-libstdc++} in the top-level
-directory, then @samp{make install-target-libstdc++}.
-
-If you have already removed the build tree, you may just remove
-@file{libstdc++.so.2.10.0} from the install tree and re-create
-it with the command 
-@samp{gcc -shared -o libstdc++.so.2.10.0 -Wl,-all,-lstdc++,-lgcc,-none -lm}.
-If the @file{ieee}
-sub-directory exists, repeat this command in it, with the additional
