Hi there. Since I usually do lots of compile-clean-compile runs, I was very 
annoyed with cleanup.sh taking too long to compile. I have thus enhanced it a 
bit to traverse the source tree less times, and to call file on less files. 
The result is several times faster (from 25-27 to 3-4 seconds on my 
computer). However my find-fu is not that good, so I'm wary of commiting it 
directly to CVS. I haven't found any problems, though.

Attached is the modified cleanup.sh so you can take a look at it, and 
eventually it ends up at the CVS (25 seconds to clean up is just too much!).
