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"
