If tcl/tk binary packages miss these headers,
that is bug on their side. So we tell people:

	This is a fault of the binary package maintainers!

Then we can create tarballs for each of the most common
tcl/tk binary packages to easily add these headers and tell people:

	For your convinience we occasionally package
	these missing header files for some tcl/tk binary
	packages as add on package: Check ...

We should avoid this at any costs.

Instead of making them official part of GRASS,
we just packages the header files. We would not need to do anything 
more than what we would need to do when we add it as official part
of GRASS. Because we do no promisse to support all tcl/tk packages,
it would save us efforts.

This would be flawed by design.
To "just" add the missing header we somehow get some sort of
responsibility that this works. We also dublicate work and add a
workaround for a bug that should be fixed at the cause.
