How is gettimeofday() used?  If it is used as an interval timer, on Windows
you can call GetTickCount() instead.

The portable solution would be to use the functions in time.h.  Cygwin should work if you just want to move a simple UNIX program to Windows, since it works with a lot of complex utilities that need to know the time of day.  Once you get Cygwin working it should feel familiar to a linux user.
I posted a more complete recommendation so I should get more points :)  Requiring a Windows user to install Cygwin in order to use your software is a pretty bad answer, so I recommended using time.h which is standard.
