I looked at patchwatcher results. Making patch [5/9] failed because after 
applying this patch should run tools/make_requests. Also should run 
tools/make_makefiles and autoheader (for regenerating include/config.h.in).

I can resend the whole series of patches with second version of [6/9] but this 
is useless before fixing this problem.

Thanks, Alexander
