Description:
Attempts to use the --mem option on Windows leads to the following, and mtr fails:

 - symlinking 'var' to '\tmp\var_auto_bszj'
The symlink function is unimplemented at mysql-test-run.pl line 2123.

How to repeat:
Run mtr with --mem option on Windows.

Suggested fix:
On Windows, the --mem option cannot work as intended and should therefore rather be ignored, after printing a message that it's not supported.

Bjørn, the patch looks good to me :)

I grabbed the patch and applied it to mysql-next-mr and tried running MTR with --mem on Windows. It now runs and displays the message you specified instead of exiting. So it seems to resolve the issue seen in PB2 for the rqg_mdl_stability test [1].
