Masa implemented the feature in CINT directly. Fons adapted it to ROOT.

did you try? it should be OK.

No. When ROOT has been installed with --enable-explicitlink, you do not need
to specify all the libs, only the top level lib.

I do not understand this point. libFumili is already used as a plug-in
see the list of plugins in system.rootrc.

This is already done (Fons). It will be documented in the Release notes.
Users can take advantage of the new tool $ROOTSYS/bin/rlibmap to create
their own map. See the Root makefile for an example.

well, if you like. Except that the world is more than just Linux. ::)
