There is *absolutely no* definitive way to know if argv0 is the
actual php script, or if it is the beginning of a query string.
Additionaly, passing parameters on the command line is
not part of CGI spec, and is not required by either
Apache or IIS.  So I have removed that code altogether,
and done some further cleanup.  Also fix pre4.3 behaviour if fix_pathinfo=0.
I've tested with IIS and Apache 1.3.27 on w2k and RH 7.3.
