There was a thread about that in the ncurses list some weeks ago.
IIRC, there are three sources for the window width info :
- a resource in the termcap/terminfo description
- the environment variable COLUMNS
- handling of the SIGWINCH signal with the associated struct.

I would not include any of the above in gcc. That's not the job of the compiler
to wrap lines at a specific line-length.  Your xterm/terminal/emacs/whatever
will care about that.
