I am thinking about going over to compile OS4 only.

The thing is that I on the one side can't use any
of the new features for a 3.x build.
And by now ignoring the extended feature-set of
OS4 would be a shame.

And since I switched over to Reaction I have the problem
that for my use of it there are way too many bugs
or flaws in the old 68k classes that will never be fixed.
Some can be worked around, some not.
