Problem compiling cvBlobsLib with OpenCV 2.4.2

edit

I am trying to compile cvBlobsLib under OpenCV 2.4.2 on Windows 7 using Visual Studio 2008. I get the following error:

1>------ Build started: Project: cvblobslib, Configuration: Release Win32 ------
1>Compiling...
1>BlobResult.cpp
1>C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\atlmfc\include\afxv_w32.h(16) : fatal error C1189: #error :  WINDOWS.H already included.  MFC apps must not #include <windows.h>
1>Build log was saved at "file://c:\Users\v00000168\Documents\Visual Studio 2008\Projects\cvblobslib_OpenCV_v8_3\Release\BuildLog.htm"
1>cvblobslib - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I have not been able to resolve it for some reason. I have been able to compile it without trouble in similar environment on Windows XP. On the same Windows 7 machine, I had previously compiled it with OpenCV 2.3.1.

Can someone please see what am I doing wrong? I have already wasted a couple of days chasing my tail here.
