As with issue 105, suggest that you build version 1.71.

See "Building the prog directory programs" [1] for instructions on how to build 
programs like converttogray on Windows. Currently building 64 bit programs is 
not supported. You could build 64 bit versions of the image libraries yourself, 
and then it's not hard to add 64bit Configurations to the VS2008 solution.
