Bug description:  Inconsistent behaviour of require_once

Description:
------------
In the code pasted below:

- top.php fails on subdir/sub.inc including "../top1.inc"
- subdir/sub.php doesn't.

Either every include should be relative to the original php file
(which would be braindead, but consistent.) In that case both
php files should fail (for subdir/sub.php the include of top2.inc
by top1.inc should fail.)

Or (and this is what I expected) include files should be relative
to the file that is including. In which case both should succeed.

Probably the same bug as http://bugs.php.net/bug.php?id=38302 , which is
labeled bogus, so I had to create a new one.

Reproduce code:
---------------
mkdir -p bug/subdir
echo '<?php require_once "../top1.inc" ?>' > bug/subdir/sub.inc
echo '<?php require_once "sub.inc" ?>' > bug/subdir/sub.php
echo '<?php require_once "subdir/sub.inc" ?>' > bug/top.php
echo '<?php require_once "top2.inc" ?>' > bug/top1.inc
touch bug/top2.inc

Expected result:
----------------
Neither top.php nor subdir/sub.php should generate errors (or both
should.)

Actual result:
--------------
Warning: require_once(../top1.inc) [function.require-once]: failed to open
stream: No such file or directory in /var/www/bug/subdir/sub.inc on line 1

Fatal error: require_once() [function.require]: Failed opening required
'../top1.inc' (include_path='.:/usr/share/php:/usr/share/pear') in
/var/www/bug/subdir/sub.inc on line 1
