Description:
------------
in the code below
$cmd='"C:/Programme/MySQL/MySQL Server 4.1/bin/mysql.exe" --execute=status';
works, but
$cmd='"C:/Programme/MySQL/MySQL Server 4.1/bin/mysql.exe" --execute="status"';
does not. The error message is:
failed with return-code: 1
Der Befehl "C:/Programme/MySQL/MySQL" ist entweder falsch geschrieben oder konnte nicht gefunden werden.

This is very strange, since running the command in a cmd box in Windows works in both cases.

Reproduce code:
---------------
$_output=array();		
$cmd='"C:/Programme/MySQL/MySQL Server 4.1/bin/mysql.exe" --execute="status"';
exec($cmd,$_output,$_retval); 
if ($_retval==0) {
   echo 'and done !<br />';
}	else {
echo " failed with return-code: ".$_retval;  		
foreach($_output as $_outputline){
  echo("$_outputline<br />");
}	


Expected result:
----------------
exec should work in both cases

Actual result:
--------------
failed with return-code: 1
Der Befehl "C:/Programme/MySQL/MySQL" ist entweder falsch geschrieben oder konnte nicht gefunden werden.

it's not a PHP but a cmd.exe problem:

""C:/Programme/MySQL/MySQL Server 4.1/bin/mysql.exe" --user=smartrqm --password=6y-app% --database=smartRQM --execute="status""

works. This is due to the way cmd /c works which is obviously used internally. See cmd /help on how cmd.exe handles quotes

broken in 5.2.6
tested 5.3.0alpha2, and now works.

simply used 
  system('"fr" "ed"');
with procmon from sysinternals to see what is executed.

5.2.6 shows
  cmd.exe /c "fr" "ed"
5.3.0alpha2 shows
  cmd.exe /c ""fr" "ed""
