stop when building

[no1xsyzy]

gives such warning

gcc -Wall -Wextra -o dns_proxy dns_proxy.c
dns_proxy.c: In function ‘reaper_handle’:
dns_proxy.c:148:25: warning: unused parameter ‘sig’ [-Wunused-parameter]
 void reaper_handle (int sig) {
                         ^

is it essential or just remove all warnings flags?

It is an unused parameter, so you can easily remove it.

(Note that this project seems to be dead, as @jtripper is not reacting on issues or anything, I created a downstream fork and adopted the AUR package)
