It doesn't change the logic of the 2006 patch, but it still seems wrong to me 

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

Shouldn't the generated libtool script be figuring out whether to add -lCstd 
-lCrun every
time it is called? Assuming the configure time CXX will be the only one ever 
used is not
ideal; and, worse, CXXFLAGS are not stored in libtool in any circumstance, and 
yet configure
determines the value of postdeps based on configure time CXXFLAGS contents.

Am I missing something, or is it better to move this machinery into libtool 

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.
