failed to compile qt mobility 1.1.0 (with qt 4.7.1, msvc2005)

what I have done:
1. add the bin path of qt 4.7.1(wincewm60professional-msvc2005) to Path.
2. enter Visual Studio 2005 Command Prompt
3. setcepaths wincewm60professional-msvc2005
4. configure -prefix "different folder from working folder"
5. nmake

then the console give me errors:

ipc\qremoteserviceregister_ls_p.cpp(57) : fatal error C1083: Cannot open include file: 'sys/types.h'
: No such file or directory


<sys/types.h> seems not available under wince

WinCE is not listed in the compatibility list for Mobility so it's probably not supported.
