Hi Ravinder,

I tried your solution here is what it displays..
stlib='smb_static bsd z resolv rt' this line still shows..
Code:
[root@xx-xx--xxx source]# tac reptest | awk 'FNR!=2 && FNR!=3' | tac
if bld.env.SAMBA_DIR:
    bld.program(target='winexe-static',
        source='winexe.c svcinstall.c async.c winexesvc32_exe.c winexesvc64_exe.c',
        includes=bld.env.SAMBA_DIR + '/bin/default/include/public',
        cflags='-pthread -include ' + bld.env.SAMBA_DIR + '/bin/default/include/config.h',
        linkflags='-pthread',
        stlibpath=bld.srcnode.abspath() + '/smb_static/build',
        stlib='smb_static bsd z resolv rt',
