WFM:

$ /bin/ldd /bin/ls
         ntdll.dll => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x77c90000)
         kernel32.dll => /cygdrive/c/Windows/system32/kernel32.dll 
(0x77a70000)
         KERNELBASE.dll => /cygdrive/c/Windows/system32/KERNELBASE.dll 
(0x7fefdb10000)
         cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)
         cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3d4e00000)
         cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3d8b50000)

See above.

ldd is meant to be compatible with the Linux tool.  As Andrey mentioned, 
use cygcheck instead if you want that layout.
