Public bug reported:

In Hardy alpha1, after install the package libc6-dev, which version is 
2.7-4ubuntu1, build the netperf tool, the build will be failed with the error:
    netlib.c:1725: undefined reference to '__CPU_ZERO'
    netlib.c: 1727: undefined reference to '__CPU_SET'

check the file: /usr/include/sched.h in the libc6-dev(2.7-4ubuntu1)
    the define change to:
    # define CPU_SET(cpu, cpusetp)           __CPU_SET_S(cpu, sizeof 
(cpu_set_t), cpusetp)
    # define CPU_ZERO_S(cpu, setsize, cpusetp)   __CPU_ZERO_S(cpu, setsize, 
cpusetp)
    # define CPU_SET_S(cpu, setsize, cpusetp)   __CPU_SET_S(cpu, setsize, 
cpusetp)

I have checked this on Gutsy version which use libc6-dev(2.6.1-1ubuntu10), it 
shows as below:
    # define CPU_SET(cpu, cpusetp)          __CPU_SET(cpu, cpusetp)

thanks
