RE: Autoconf 2.69 bug

[Steve Glaser]

That's fine. It was pretty easy to work around. Other stuff gets confused by 
Dropbox's convention. I've told them I'm not wild about it.

Just wanted to mention it in case it was something you wanted to look at.

I'll see if anyone on the SystemC forum claims ownership.
