[omniORB] win2k and omnithread for latest MS compilers

[Matthew Bettencourt]

I am trying to compile some client code on a windows 2000 box and i am 
running into some problems.  I am getting a missing include <windows.h>. 
  I have the full MS visual c++ 2005 express edition installed and I 
downloaded the omniORB407_win32.exe file and installed it.

Any ideas?

Just FWIW, i am not a windows guy, so sorry for the noob question.
Matt

P.S, I am compiling as following
cl /c /EHsc I . /D__x86__ /D__WIN32__ /D_WIN32_WINNT=0x0400 /D__NT__ 
/D__OSVERSION__=4  /D_CRT_SECURE_NO_DEPRECATE /I"c:\Program 
Files\omniORB4\include" ....
