Well, that is strange.  I am also on Win2k, and cygcheck --version
shows exactly the same output as yours (which isn't surprising - my
machine is pretty well up to date).

Having said that, I've never experienced the hangup which others are
reporting - though I have seen the postinstall script in question
take ages to complete on an older, slower NT box.

The dependence is coming from shlwapi.dll.  Here is some info:

$ ls -l /d/winnt/system32/shlwapi.dll
-rwxrwxr-x+   1 Administ SYSTEM     395264 Jul 13 16:05
/d/winnt/system32/shlwapi.dll

$ cygcheck /d/winnt/system32/shlwapi.dll
D:/winnt/system32/shlwapi.dll
  D:/winnt/system32\msvcrt.dll
    D:/winnt/system32\KERNEL32.dll
      D:/winnt/system32\NTDLL.DLL
  D:/winnt/system32\GDI32.dll
    D:/winnt/system32\USER32.DLL
  D:/winnt/system32\ADVAPI32.dll
    D:/winnt/system32\RPCRT4.DLL

I suspect you will see something different.  I guess if on some Windows
systems shlwapi.dll has a dependence on msvcrt.dll, it is not safe
to call this from any cygwin app.
