For both of the above, at least on ELF systems, the correct thing to do is 
to make GCC (used by any of the drivers "gcc", "g++", etc.) do the right 
thing by default: link with the libraries required by the objects being 
linked in, using those appropriate for shared libraries if -shared is 
passed, and respecting options such as -static-libstdc++.  That is, make 
the driver/collect2 combination smart enough that libtool does not need to 
query this information.
