 -static links everything statically, like system libc, X libraries
etc., not only libgcc and libstdc++.  Also the shared libstdc++.a
contains a single sharable object, and -static would include that in
full, while if you link with the static libstdc++ only the objects
needed would be included.  The best would be to put both the shared
object and the individual .o files into libstdc++.a, or make
libstdc++.a static and libstdc++_s.a shared and provide a
-static-libstdc++ option, just like there is already a -static-libgcc
option.
