Thanks.

To me as well, but it seemed more likely to work if I only suggested a 
small change ;-)

I guess it would be better to have it either completely in libtool (figure 
it out for each invocation) or completely in autoconf (let it add 
-library=Cstd to LDFLAGS for shared libraries), or not at all and let 
users specify CXX="CC -library=Cstd"... I don't have a strong opinion 
there.
