I neglected to try to compile with optimization... my mistake. Fix pushed.

main.c:2169:11: error: ‘num_mkfiles’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

I've been bitten by false-positives from that warning in the past, which is probably not unrelated to why it's not happening on Paul's doubtless-later compiler, but I think it has a point here:
