building Postgresql in Windows XP

Dear Sir,
I am trying to build PostGreSql from
http://www.postgresql.org/ftp/source/v8.3.6/. However, I am unable to
find any complete step by step document how to build it in windows xp. I
would be grateful to you if you could point me any URL that can guide me
toward a successful compiling of the database.

I want to thank you in advance

Sincerely yours
Md. ABdur Rahman
