Possible, yes, but not practical.  Windows already has a mechanism
(dlls) so the gains aren't worth the effort.  If you want real shared
libraries, get Interix, which runs on the posix side of NT, or get
Linux.

Yes.  Windows resolves those issues when it loads the DLLs.  Your
program doesn't even need to know that B and C use A, since it only
sees the import libraries, not the whole DLL's objects.
