Exactly.  "B" is the "*compilation*" buffer in my case.  I need two
things from the window:

 1) The window should be dedicated to *compilation*

 2) The window should stick at the bottom

The size isn't really important, since I change it frequently anyway.

I agree that window-dedicated-p only promises me the first, but Emacs
21 gave me the second and Emacs 22 doesn't.  This make Emacs 22 less
useful and I reported the problem.

A window-local "unsplittable" flag that I can set could probably help.

I'm attaching the actual code I'm using, although the simple test case
I gave you shows the change.

Put these three files in your load-path and load compile-window.  Then
run a compilation with M-x compile.  You'll get a *compilation* window
that you can resize with "C-c ." which sticks to the bottom and stays
there.
