Hi Abhash,

I left comments on v1.  Even for a compile issue like this one, maybe just
a quick reply to the earlier posting saying what you will change is more
appropriate than sending a new version just one day after the first.

Not a bit thing, so just check those reviews on v1.

Thanks,

Jonathan
