"libintl-8.dll" should NOT be in \cygwin\bin -- and a cygwin-compiled
application should not be looking for it. The *cygwin* version of the
i18n library is "cygintl-8.dll", which is found in the "libintl8"
package. I'm assuming this was simply a typo...if not, then you've
somehow picked up a mingw version of the i18n library.

Windows uses the following algorithm to find DLLs:
1. look in the same directory as the .exe
2. look in the current directory
3. look in the windows system directory (C:\Windows\system32\)
4. look in the windows directory (C:\Windows)
5. look in each of the directories in the PATH
Applications compiled using vis-studio 2005 or newer also can use binary
manifests compiled in to the .exe that explicitly specify certain other
information used to located DLLs; also, certain registry keys can affect
the search path.
But the important bits, for you, are items #1 and #5:
if you install your exe into C:\cygwin\bin, then it should work.
Or, if you set your PATH variable (My Computer->Properties->Advanced
System Settings [*]) so that it includes C:\cygwin\bin, that would work
also.
You could even exploit #2 by creating a Windows Shortcut to your
executable, but set the Start In directory of the shortcut to C:\cygwin\bin.

No, no, no, a thousand times no! Application programs should never
clutter C:\Windows...

Not for cygwin (see vis studio note, above).
