Note that this may not give a complete list.  Consider rxvt.exe:

quine% cygcheck rxvt.exe
Found: .\rxvt.exe
Found: C:\cygwin\bin\rxvt.exe
rxvt.exe
  .\cygwin1.dll
    C:\WINDOWS\System32\KERNEL32.dll
      C:\WINDOWS\System32\ntdll.dll
  C:\WINDOWS\System32\USER32.dll
    C:\WINDOWS\System32\GDI32.dll
      C:\WINDOWS\System32\ADVAPI32.dll
        C:\WINDOWS\System32\RPCRT4.dll


This might suggest that only cygwin1.dll is needed (besides the windows
stuff).  However, continuing (in X, with DISPLAY set):

quine% cd /usr/X11R6/bin
quine% mv libX11.dll libX11.dll~
quine% back
/bin
quine% ./rxvt.exe
failed to load libX11.dll

Putting libX11.dll~ back to its original name again allows rxvt.exe to run
correctly.  Thus in this case (at least) cygcheck is not finding _all_ of the
dll's that are needed.
