same error under linux

I cannot reproduce the problem under Linux with the latest pdfsizeopt.py. Please
download the newest pdfsizeopt.py and try again on Linux. Once we fix the Linux
issue, we can start investigating the Windows issue. Here is what I get on 
Linux:

line 4513, status = os.system(cmd) can not get the real status we want.

os.system(command)
Execute the command (a string) in a subshell. This is implemented by calling the
Standard C function system, and has the same limitations. Changes to os.environ,
sys.stdin, etc. are not reflected in the environment of the executed command.

On Unix, the return value is the exit status of the process encoded in the 
format
specified for wait(). Note that POSIX does not specify the meaning of the return
value of the C system function, so the return value of the Python function is
system-dependent.

On Windows, the return value is that returned by the system shell after running
command, given by the Windows environment variable COMSPEC: on command.com 
systems
(Windows 95, 98 and ME) this is always 0; on cmd.exe systems (Windows NT, 2000 
and
XP) this is the exit status of the command run; on systems using a non-native 
shell,
consult your shell documentation.

As I said before, please run it on Linux, and please report what you get, and 
if they
are correct.
