Description:
------------
When virtual() calls another page that contains 
require('./xyz'), the require() call breaks.  But it 
works with require('xyz'), which smells really bad, and 
makes me think this is a bug and not just me missing 
something.

Posted this to php-general, but got no feedback.

Reproduced on OS X 10.3.6 + Apache 1.3.29 + PHP/4.3.4, 
and on Debian + Apache 1.3.31 + PHP/4.3.9-1.

Reproduce code:
---------------
------ foo.php ------
This is foo.
<?php virtual('subdir/bar.php'); ?>

------ foo.shtml (my "control group") ------
This is foo.
<!--#include virtual="subdir/bar.php"-->

------ subdir/bar.php ------
This is bar.
<?php require('./baz.php'); ?>

------ subdir/baz.php ------
This is baz.


Expected result:
----------------
This is foo.
This is bar.
This is baz.

[Note: foo.shtml correctly produces this output; foo.php 
should in theory work identically, but does not.]

Actual result:
--------------
This is foo.
This is bar.
Warning: main(./baz.php): failed to open stream: No such 
file or directory in /blah/blah/subdir/bar.php on line 2

Fatal error: main(): Failed opening required './baz.php' 
(include_path='.:/usr/local/lib/php') in /blah/blah/
subdir/bar.php on line 2


Oddly, it works if bar.php says require('baz.php') 
instead of require('./baz.php').
