Tunslip6 error

While doing border router experiment when I type the command "make tunslip6" , it is showing the following error :

cc tunslip6.c -o tunslip6
tunslip6.c:120: warning: implicit declaration of function 'gettimeofday'
tcc: error: undefined symbol '__dso_handle'
make: *** [: tunslip6] Error 1
