Sorry, but I don't care whether this bug will be fixed or not.

The server is not mine to mess with so I can't install another PHP
version.

Description:
------------
If you have a directory where Everyone has "Full Control" rights you
would expect is_dir to return true but it doesn't.

This bug has existed since 5.0.0 and I've had this problem on at least
three servers during the past year.

I'm lying about my PHP version (it's really 5.1.4) but I've checked the
change log.

realpath() seem to exhibit the proper behavior.

Reproduce code:
---------------
<?php
print("<pre>");
error_reporting(E_ALL);
#clearstatcache();

$paths = array(
	"C:\\",
	"C:\\Windows",
	"C:\\Windows\\Temp",
	"C:\\Windows\\Temp\\RP_Compile",
	"C:\\Windows\\Temp\\DoesNotExist",
	"C:\\Windows\\Temp\\RP_Compile\\Subdir",
);

print("\nis_dir()\n");
foreach($paths as $path)
	print(is_dir($path) . " \t$path\n");

print("\nrealpath()\n");
foreach($paths as $path)
	print(!(realpath($path) === FALSE) . " \t$path\n");

print("\nstat()\n");
foreach($paths as $path)
	print(!(stat($path) === FALSE) . " \t$path\n");

print("</pre>");
?>


Expected result:
----------------
is_dir()
1 	C:\
1 	C:\Windows
1 	C:\Windows\Temp
1 	C:\Windows\Temp\RP_Compile
 	C:\Windows\Temp\DoesNotExist
1 	C:\Windows\Temp\RP_Compile\Subdir

realpath()
1 	C:\
1 	C:\Windows
1 	C:\Windows\Temp
1 	C:\Windows\Temp\RP_Compile
 	C:\Windows\Temp\DoesNotExist
1 	C:\Windows\Temp\RP_Compile\Subdir


Actual result:
--------------
Notice the different result for "C:\Windows\Temp\RP_Compile"

is_dir()
1 	C:\
1 	C:\Windows
1 	C:\Windows\Temp
 	C:\Windows\Temp\RP_Compile
 	C:\Windows\Temp\DoesNotExist
1 	C:\Windows\Temp\RP_Compile\Subdir

realpath()
1 	C:\
1 	C:\Windows
1 	C:\Windows\Temp
1 	C:\Windows\Temp\RP_Compile
 	C:\Windows\Temp\DoesNotExist
1 	C:\Windows\Temp\RP_Compile\Subdir
