For whatever reason, Dinkumware aren't exporting the std exception classes
from the runtime dll in VC7 - instead the class is defined "all inline" and
this is what is creating the warnings. The next release will suppress the
warning, but whether that's a good idea or not I'm not sure.

Smaller code size - you only link to what you're actually using (and there's
dll to redistribute).

No idea, probably best to ask on a VC specific newsgroup.

Only a little on the way the names are generated - see
What else do you need?

Yes, at gmane.org.
