Yeah, if I recall correctly that was the reason why I removed "-I.",
because of conflicting header names. Maybe just rename headers to
screen_pty.h etc. Other which I think may be conflicting are sched.h and
tty.h, so they would be screen_sched.h, screen_tty.h. It's bit ugly but
hard to get conflicting names then. Although if I started prefixing
headers, I would just prefix them all for consistency... on the other
site it's useful to have headers with same names as .c files.

Definitely something to spend some time thinking on.
