Rebuilding toolchain/system/world after updating linux-headers from 2.6.22-r2 to 2.6.23, I ran into this build error: x86_64-pc-linux-gnu-gcc -march=k8 -O2 -pipe -ggdb -msse3 -Wstrict-prototypes -Wall -D_GNU_SOURCE rdisc.c -lresolv -o rdisc x86_64-pc-linux-gnu-gcc -march=k8 -O2 -pipe -ggdb -msse3 -Wstrict-prototypes -Wall -D_GNU_SOURCE arping.c -lresolv -o arping rdisc.c: In function 'do_fork': rdisc.c:251: error: 'OPEN_MAX' undeclared (first use in this function) rdisc.c:251: error: (Each undeclared identifier is reported only once rdisc.c:251: error: for each function it appears in.) make: *** [rdisc] Error 1 make: *** Waiting for unfinished jobs.... !!!

Google is not especially informative on this error ;-). This failure is not a big problem for me, but this should probably block bug #195298.
