[LEDE-DEV] [PATCH firewall3] utils.h: Avoid name clashes for setbit/delbit/hasbit

Florian Fainelli f.fainelli at gmail.com
Thu Sep 1 19:10:15 PDT 2016


Rename to fw3_{set,del,has}bit to avoid name clashes with sys/param.h:

/opt/toolchains/stbgcc-4.8-1.5/arm-linux-gnueabihf/sys-root/usr/include/sys/param.h:80:0: note: this is the location of the previous definition
 #define setbit(a,i)     ((a)[(i)/NBBY] |= 1<<((i)%NBBY))
