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',
