tao_idl Will Create a Directory Each Time a -o* Option is Passed

[iguessthislldo]

As stated in the title, tao_idl will immediately create the directory specified by an -o option and its alternative forms:

ACE_TAO/TAO/TAO_IDL/be/be_global.cpp

Lines 3033 to 3037 in d055988

	case 'o':
	if (av[i][2] == '\0')
	{
	idl_global->append_idl_flag (av[i + 1]);
	int result = ACE_OS::mkdir (av[i + 1]);

This means it can do this:

$ tao_idl -o x -o y -o z
IDL: No input files
$ ls
x  y  z

Now obviously you really shouldn't be passing multiple -o options to tao_idl, but at the same time tao_idl shouldn't be doing this. It should just take the last one and use that, ideally only making the directory right before it writes the files there. I might try to fix this at some point, but I'm filing this issue mostly just to document it.
