I have a file with one int per line and when reading it with:

            let x = (Scanf.fscanf log "%d" (fun n -> n)) in
            let y = (Scanf.fscanf log "%d" (fun n -> n)) in
            let w = (Scanf.fscanf log "%d" (fun n -> n)) in
            let h = (Scanf.fscanf log "%d" (fun n -> n)) in
	   ....

it works in 3.09, but 3.10 fails with: 
Exception: Scanf.Scan_failure "scanf: bad input at char number 1: \n"

so I must change the format string to " %d " (note the spaces around
%d) to eat the newline too, is this a desired change?
( the c version reads the numbers with just "%d", I'm not sure what's
the correct behavior)

cheers,
 Michael
