Bingo.  I think we have different service packs applied or something.  I'm
getting the following on my machine:

$ cygcheck -s | head -5

Cygwin Win95/NT Configuration Diagnostics
Current System Time: Sun Oct 05 15:46:24 2003

Windows 2000 Professional Ver 5.0 Build 2195 Service Pack 2
$ ls -l /mnt/c/WINNT/system32/shlwapi.dll
-rwxrwxr-x+   1 Administ SYSTEM     300816 Oct 20  2000 /mnt/c/WINNT/system32/shlwapi.dll*
$ cygcheck /mnt/c/WINNT/system32/shlwapi.dll
c:/WINNT/system32/shlwapi.dll
  c:/WINNT/system32\GDI32.dll
    c:/WINNT/system32\NTDLL.DLL
    c:/WINNT/system32\KERNEL32.DLL
    c:/WINNT/system32\USER32.DLL
  c:/WINNT/system32\ADVAPI32.dll
    c:/WINNT/system32\RPCRT4.DLL
$

Curiously enough,

$ cygcheck /cygdrive/c/WINNT/system32/shlwapi.dll
C:/cygwin/cygdrive/c/WINNT/system32/shlwapi.dll - Cannot open
$

It looks like cygcheck's mount processing code doesn't understand the
cygdrive prefix...
