Hi Workers!

There is a little bug in system():

  if (sys_flags & __system_use_shell)
    shell = getenv ("SHELL");
  if (!shell)
    shell = comspec;

After this there should be an

  if (!shell)
    shell = command_com;

like in _shell_command(), because _is_unixy_shell() can receive
a NULL pointer which list_member() will dereference, if there is no 
SHELL or COMSPEC environment variable (this is the case in a perl
test script).

bye, Laszlo
