In which directory? main.c could be anything?

Okay; "struct winsize" isn't actually specified by POSIX, but it
should exist somewhere if TIOCGWINSZ is defined. Not necessarily in
the same header as the TIOCGWINSZ definition. Again, it may be guarded
by a #if/#ifdef.

On Linux, it's defined in both asm-generic/termios.h (kernel header)
and bits/ioctl-types.h (glibc header).
