Windows uses the PATH variable to find DLLs. If c:\windows\system was in
the path before c:\cygwin\bin, the DLL in \system will be found instead.
There's no special Cygwin magic here.

Only if you have "." in your PATH.
Generally, Windows apps look in their directory (the one that contains the
executable), and then search the PATH. The best solution to be able to
run Cygwin applications from anywhere is to add "c:\cygwin\bin" to your
global Windows PATH (you can add it at the end).
