Hello!
I wondered today once more why the mode-line of a *compilation* buffer
with column-number-mode on showed "??" as line number. A discussion on
the Help-gnu-emacs list with Eli Zaretskii revealed:

This buffer switching did not enable the line numbers, maybe because
of only changing between two buffers in the same frame. Meanwhile,
having line-number-display-limit-width increased to an insane value of
62,500 t\x05he line numbers counter works continuously. A new default
value of 24 K should be OK – this is the maximal line length I almost
encountered while compiling QT4. The line counter seems efficient
enough that I did not encounter any loss in the speed of compilation
or more heat produced by the CPU of my portable.
Up-to-date shell interpreters support command line lengths of 64 K,
maybe even 128 K, to support software like QT4 or GTK+2 or based on
these, so GNU Emacs should also update.

Upgraded, adj.:
Didn't work the first time.
