OK, I'm not sure why you sent this again to the list when I answered the 
same query that you sent me off-list.  But in the interest of complete
symmetry, I'll cut and paste the response I already gave you privately.


------------- cut and paste --------------------------------------------

OK.  First, you shouldn't need to list -lcygwin.  It gets added automatically.
Fortunately now, it should be harmless to list it however.  That hasn't always
been the case so it's good not to get in the habit of adding it when it's not
needed.

'GetModuleHandle()' is a Win32 API.  You apparently have not installed the 
w32api package.  Rerun setup and do so.
