about the -zscores bug

Hi,

First of all thank you for making this very nice software publicly available.
I use to cluster mesh terms from Medline and it works really well and really fast.

I do have one problem though. And this is about the bug that happens when you supply the -zscores option in scluster.
It produces an empty clustering file (both on Win and Mac).
I noticed that the bug was reported on the bigtracker more than a year ago (this is why I post the bug here).
The person that reported the bug suggested that the problem is just an fclose() that is missing (and that seems very likely).

I would really like to use these z-scores in my work.

kind regards,
Sven Degroeve
