[PHP-INST] PHP 4.04 install binary Win32 and MSQL 7.0

[Come Italia s.r.l. - Webmaster]

I've installed and correctly configured (I suppose) the binary version of 
PHP 4.04 on a Win NT server with Microsoft IIS.
I'm using CGI version of IIS.
when I try to connect my script with Microsoft SQL 7.0 DB I get this error 
"Fatal error: Call to undefined function: sybase_pconnect() in 
./db/sybase.php on line 17"
This means that the binary version of PHP doesn't support SQL 7.0??
Must I compile the source code of PHP?
Thanks a lot
