Thank you, Andreas and the other, for your contribution. As you probably
have guessed, I currently don't have very much time to spend on tkimg. All
I did was supply 2 bug-fixes (for bugs #565784 and #571827, which are
attached to the resp. bug-reports) but I didn't even have time to set up
CVS to commit those myself ;-(

I would personally prefer option 2b1 because it takes less work, but I
agree with Andreas that 2b2 would be better. The disadvantage of 2b2 is
that we would create our own version of the support libraries, which means
we would have to support those modifications until the original group
accepts them in the official distribution. Many systems already have the
support-libraries on board, so we cannot depend on the availability of the
Stub-table. Because of this maintainance, Img currently tries to implement
2b1.

The disadvantage of 2b1 is that other packages like Trf and TrfCrypt need
the same functionality. This would suggest preparing a TIP for inclusion
in Tcl (8.5 or 9.0), which I definitely would be in favor of! This would
also open the way to use the VFS system, so dll's can be loaded
dynamically from other file systems. We would get a variant of 2b1: "Via
explicit usage of the dyn.loader provided by Tcl".

However, Andreas' different options don't exclude each other, as he
already notes: On systems without dynamical linking, statical linking is
the only option. And if some support library starts to provide a kind of
Stub-table, that would surely be advanteouge to use.
