Link error with WinDDK 6000

We have kernel mode drivers with IPP 2.0 which can be build sucessfully using WinDDK 6000 Vista/Longhorn environment.
Recently, we're trying to move to IPP5.3 with the same environment but got a link error:

LIBCNTPR.LIB(sqrt.obj) : warning LNK4006: __CIsqrt already defined in ntoskrnl.lib(ntoskrnl.exe); second definition ignored
LINK : error LNK1218: warning treated as error; no output file generated

The Sources file was checked regarding the TARGETLIBS setting:
TARGETLIBS= $(SDK_LIB_PATH)\LIBCNTPR.LIB \
$(DDK_LIB_PATH)\PORTCLS.LIB

Is there any suggestion of this error?
Thanks.

Note, the latest version is IPP 6.0. Please check with IPP kernel mode sample on how to use IPP in kernel mode drivers.
