Dan McGee found the following compile error:
gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes -Wall -I../include
-DRESOLVE_HOSTNAMES -DLIBDIR=\"/usr/lib/\" -c -o ipnetns.o ipnetns.c
ipnetns.c:31:12: error: static declaration of ‘setns’ follows non-static
declaration
/usr/include/bits/sched.h:93:12: note: previous declaration of ‘setns’
was here
make[1]: *** [ipnetns.o] Error 1
