Of course, I mean crunched variant where whole library packed.

It is termcap implementation details. The less anything (including 
sources) knowns about it, the much better.

I talk not about binaries compatibility, but about mass Makefiles 
reediting.

Yes.

Not every platform have ncurses.

I am against it for the reasons I already explain, it put our sources into 
unneded implementation details deeps.
