Just compiled 4.1 with,
'./configure' '--with-fastcgi' '--disable-mysql' 
'--enable-inline-optimizations' '--disable-debug' 
'--with-pdflib=no' '--disable-xml' '--with-pgsql' 
'--with-zlib' '--enable-exif'

With Zeus Webserver 3.8

Now on phpinfo();

php var names have changed from vars like
HTTP_SERVER_VARS["argv"]  >> _SERVER["argv"]
or 
HTTP_ENV_VARS["USER"]    >>   _ENV["USER"]
