Description:
------------
I cannot compile with support for Unix98 pty.

Following is source code from ext/standard/proc_open.c line 64 to 68.

#if 0 && HAVE_PTSNAME && HAVE_GRANTPT && HAVE_UNLOCKPT && HAVE_SYS_IOCTL_H && HAVE_TERMIOS_H
# include <sys/ioctl.h>
# include <termios.h>
# define PHP_CAN_DO_PTS 1
#endif

I think that '#if 0 && HAVE_PTSNAME ...' is wrong, '#if HAVE_PTSNAME ...' is right.


Reproduce code:
---------------
$descriptorspec = array(
  0 => array("pty"),
  1 => array("pty"),
  2 => array("pty")
);

$cwd = '/tmp'; 
$env = array('some_option' => 'aeiou');

$process = proc_open('php', $descriptorspec, $pipes, $cwd, $env);

Expected result:
----------------
No error.

Actual result:
--------------
PHP Warning:  proc_open(): pty pseudo terminal not supported on this system in xxxx.php on line xx

It has been disabled by Wez intentionally (unfortunately I don't know the exact reason why).
Assigned to him, maybe he can add some comments.

It was disabled because Sascha didn't think the configure check was good enough.

Following is a part of http://www.php.net/proc_open.
"PHP 5 introduces pty support for systems with Unix98 ptys. "

If it is not possible to use pty, should we change the document? Or, is there any plan to modify the configure script?
