Problem:
 When the command line passed to passthru contains more than
 one argument that is quoted, the command line is not run.
 For example:

 passthru("\"C:\\Some dir\\prog.exe\" arg"); -- works
 passthru("\"C:\\Some dir\\prog.exe\" \"new arg\""); --fails

Systems tested:
 Windows NT 4.0 and Windows 2000
 Apache 1.3.22 with php4apache.dll
 PHP versions 4.1 and 4.1.1 (problem not present w/ 4.06)
 PHP and Apache are the distributed Windows binaries
 safe_mode is off

Example script:
<html>
<head>
<title>PHP Test Script</title>
</head>
<body>

<h1>PHP Test Script</h1>

<?php
function write_example($command)
{
  // Write a  header.
  echo "\n<h2>Command: ", htmlspecialchars($command), "</h2>\n\n<pre>\n";

  // Run the command.
  passthru($command);

  // Finish up the section.
  echo "\n</pre>\n";

  // Done, return.
  return false;
}

write_example("test.bat");
write_example("\"test.bat\"");
write_example("\"test.bat\" arg");
write_example("\"test.bat\" \"arg\"");
?>

</body>
</html>

Contents of "test.bat" (goes in same dir as script above):
@echo Batch file run OK
