Description:
------------
I'm trying to call php-cgi.exe from inside my app, and I wanted to supply the script via a pipe.  so I set the pipe name \\.\pipe\testpipe in PATH_TRANSLATED, but php-cgi.exe won't read from there.  it failes in virtual_file_ex() being confused thinking it's a unc path, and skipping the . component, and trying to use FindFirstFile to test if valid.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

It's read by a human, we need a script or C code or at least something we can test with.

using a trivial pipes experiment available from http://louis.steelbytes.com/temp/fileAsPipe.zip

shell1:
  fileAsPipe c:\path\test.php \\.\pipe\test

shell2:
  set GATEWAY_INTERFACE=CGI/1.1
  set REQUEST_METHOD=GET
  set PATH_TRANSLATED=\\.\pipe\test
  set SCRIPT_NAME=test.php
  php-cgi.exe

shell2.output:
  Status: 404 Not Found
  X-Powered-By: PHP/5.2.6
  Content-type: text/html

  No input file specified.

note:  this is arguably not a bug, but really a feature request :)

more notes:
* using php.exe -f \\.\pipe\test also does not work
* also using \\mypc\pipe\test does not work

Reclassified. This most likely will never be implemented. You really should be using the FastCGI interface anyways.

Is this still an issue with any of the actively supported PHP
versions[1]?  And is it still relevant for you?
