-V is broken.  Some still want to fix it; others want to deprecate and
remove it.  In this case, too much C++ stuff lives outside the control of -V.
Specifically, the header files.

In any case, we cannot support arbitrary compiler + library combinations.
The libstdc++ for 3.0 cannot be used with a much older compiler.  Using the
much older library with the 3.0 compiler might work, but I don't think
anybody's tested it (would anybody care?) to see.  You should old compiler +
old library, or new compiler + new library.

Once 3.0 is released, then libraries should be a *bit* more "hot pluggable" I
think.  The main issue is again the header files.  Patches are welcome.  :-)
