Chris,

I noticed that some/many projects in GGL have warning level set down to 
level W1, so ensure you compile with level W3. I personally prefer to 
compile all my code as level W4 plus (very important)
language extensions disabled
(http://msdn.microsoft.com/en-us/library/0k0w269d.aspx)

I think it's reasonable for library like GGL, which is not
specific to Win32.

What versions you exactly mean?

The generator program should put this here:

boost::ignore_unused_variable_warning(proj_param);
