It is true that dependency information may be lacking from the 
convenience libraries but ultimately the program needs to be linked 
using the C++ compiler in order to be sure that everything will work. 
G++ usually adds libstdc++ as an implicit dependency so the linkage 
should work.

I am not excusing libtool for not listing libstdc++ as a dependency. 
It may be that the missing dependency information is actually due to 
GCC not specifying it as a dependency since libtool typically obtains 
this information from GCC.  Linux is usually resistent to specifying 
explicit dependencies so it may be that GCC does not list this 
dependency on Linux but it does on Solaris.
