Elavazhagan,

Also, current SVN checkout compiles for me with Visual C++ 2005.
By the way, here you can find my Visual C++ 2005 project files to
compile GEOS:

http://mateusz.loskot.net/projects/geos/

see first bullet under GEOS 3.0.0.
Download it, check README file, put sources into 'geos' directory and it
should work.
