This code fails to compile on the following system:
https://build.opensuse.org/package/live_build_log/home:ldv_alt/strace/RedHat_RHEL-5/x86_64

pidns.c: In function 'pidns_test_init':
pidns.c:204: error: 'CLONE_NEWUSER' undeclared (first use in this function)
pidns.c:204: error: (Each undeclared identifier is reported only once
pidns.c:204: error: for each function it appears in.)
pidns.c:204: error: 'CLONE_NEWPID' undeclared (first use in this function)

A similar compilation issue exists in fork--pidns-translation.c, too.
