it works as expected for me:
$ ldd /usr/bin/ls.exe
ntdll.dll => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x77410000)
kernel32.dll => /cygdrive/c/Windows/system32/kernel32.dll (0x771f0000)
KERNELBASE.dll => /cygdrive/c/Windows/system32/KERNELBASE.dll
(0x7fefd460000)
SYSFER.DLL => /cygdrive/c/Windows/System32/SYSFER.DLL (0x74e90000)
cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)
cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3e1840000)
cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3e6e90000)
$ objdump -x /usr/bin/ls.exe |grep "DLL Name:"
DLL Name: cygwin1.dll
DLL Name: cygintl-8.dll
DLL Name: KERNEL32.dll
