I run PHP via a simple-minded webserver which sets up some environment
variables and then calls my php scripts (which begin with a
"#!/usr/local/bin/php" line).  My scripts must handle all the headers,
including the HTTP status header.  My standard included file contains
"header($_SERVER['SERVER_PROTOCOL'] . ' 200 OK');", and other files may
emit a similar header with a different status code for redirection and
so forth.

Unfortunately, after upgrading to 4.3.2 I encountered two problems.
First, PHP was refusing to emit status headers for which the status code
was 200 even when explicity instructed to by the above header() call.
Second, while my scripts would run correctly at the command line, when
run via a web server I was getting a 404 status and the error message
"No input file specified."

I have created a patch to work around the above problems; it is a hack,
but restores my desired functionality if I also set "cgi.rfc2616_headers
= 1" in php.ini.  Please consider backing out rev 1.195 of
php4/sapi/cgi/cgi_main.c or adding a configuration directive to disable
its behaviour.  I'm not sure what the correct solution for the "No input
file specified" problem is; I'll try to look into it more if I have some
time next week, but this was my first peek at PHP's source.
