ld: warnings

I got a whole bunch of ld warnings but gdl built ok and is running fine.

@jaymurthy please look internet searching for the first top error... Apparently some OSX hiccup. The last errors refer all to lib::file_move may disappear once the first problems are solved.
In all cases, these are warnings and fortunately not blocking.
