For all systems, you can find one example of makefile illustrating
how to create a shared lib or (DLL) for all systems in
$ROOTSYS/test/Makefile.
In case of NT, Valery Fine invested a lot of his time to understand
how to build a DLL without modifying the class definition too much.
He proposed the clever introduction of the EXTERN (now R__EXTERN)
statement for the definition of the DLLIMPORT statement on NT.
He published a note on his work that you can find in the proceedings
of CHEP97.
I would suggest to Valery to have a copy of his paper also available
on the web.
