Subject: Re: [PATCH] libipt_ULOG.c - include strings.h for the definition of ffs()

note: I guess it could also be bionic vs libc header files...
but per man ffs:
http://man7.org/linux/man-pages/man3/ffs.3.html

       #include <strings.h>
       int ffs(int i);

       #include <string.h>
       int ffsl(long int i);
       int ffsll(long long int i);

strings.h is the right header file.
