Bug description: file_exists strange behavior on windows platform only
Description:
------------
Concat directory name without trailing dir separator, and a file name.
While i was ready to prepare a new release of PEAR_PackageFileManager
(PFM), and generate the new package.xml, i found a bug. I thought first it
was from PFM, but then i investigate a bit more, and i found :
It will occurs only under Windows platform, because it works fine under
Unix.
I have :
- this "E:\pearix-dev\pfm15x" directory exists
- this "E:\pearix-dev\pfm15xpackage.xml" (file | dir) does not exists
- my test script into "E:\pearix-dev\pfm15x" directory
Tested under PHP 5.1.4 and PHP 4.4.2 under windows, with Apache 2.0.55
gave WRONG results
Tested under PHP 5.1.4 and PHP 4.4.0 under Unix with Apache 2.2.2 gave
GOOD (expected) results.
Feedback are welcome !

Reproduce code:
---------------
<?php
$outputdir = dirname(__FILE__); // "E:\pearix-dev\pfm15x"
$packagefile = 'package.xml';
var_dump($outputdir);
var_dump($outputdir . $packagefile);
if (file_exists($outputdir . $packagefile)) {
var_dump('condition 1 passed');
}
if (is_writable($outputdir . $packagefile)) {
var_dump('condition 2 passed');
}
if ((file_exists($outputdir . $packagefile) &&
is_writable($outputdir . $packagefile))) {
var_dump('condition 3 passed');
}
?>
Expected result:
----------------
None of "condition x passed" message displayed, but only
string(20) "E:\pearix-dev\pfm15x"
string(31) "E:\pearix-dev\pfm15xpackage.xml"
Actual result:
--------------
The 3 conditons are TRUE
string(20) "E:\pearix-dev\pfm15x"
string(31) "E:\pearix-dev\pfm15xpackage.xml"
string(18) "condition 1 passed"
string(18) "condition 2 passed"
string(18) "condition 3 passed"
