Another aspect of the Windows Thing which I have not seen discussed yet 
is the DLL load path: http://goo.gl/VA8yC

Since Windows looks for DLLs first in the *.exe directory, this is the 
most reliable place to put them.

Options 2-5 in the list at the page linked above don't really apply 
here.  Cygwin purposely keeps itself nice and segregated from the rest 
of the system, so installing DLLs under c:\Windows isn't an option, and 
CWD is simply useless for our purpose here.

The only thing stopping us from using the final option in the article 
(i.e. putting cyg*.dll somewhere else in the PATH) is that it would put 
the DLLs off in the most fragile location allowed under the rules and it 
wouldn't solve the OP's problem anyway.  The DLLs would still appear in 
file name completion lists, since that also searches the PATH.
