I am compiling ffmpeg under cygwin with -mno-cygwin, and then linking 
the resulting static libs under MSVC 2005 edition.  There are three 
symbols that remain undefined at link time:


This patch addresses _gettimeofday.  It is supplying a microsecond 
resolution time value for general use.  Under cygwin, the resolution of 
_gettimeofday is much more coarse, on the order of 10ms.  Also, as noted 
above, this breaks linkage with the MSVC runtime.  Instead, we can use a 
high resolution timer calls in the win32 api.
