Hi Ed,
No need to perform all these complicated exercises.
Attached you find a small script mklibs.txt (renamed from
mklibs.bat to satisfy some email filters) which creates
a ROOT loadable DLL of private user's classes.
It assumes the use of MSVC++ 6.0 and as you can see the compiler
options are minimal.
In addition you see that I use also a Headers.h and Linkdef.h
file. This is a "trick" to circumvent the problem that one can't
use wildcarding like *.h in the rootcint command.
These sort of scripts I am using already for years and so far
it worked without any problems.

                                        Cheers,
                                         Nick.
