"struct timeval", used by gettimeofday().

tools/timer isn't actually used by GRASS or the build system, so I
don't consider this one to be particularly critical.

A grep for "winsize" would be more useful. TIOCGWINSZ is being found,
otherwise the code which uses "struct winsize" wouldn't be compiled
and wouldn't generate an error.
