Probably because of: warning: implicit declaration of function 'fprintf' [-Wimplicit-function-declaration] src/dnsproxy.c:44:1: note: include '<stdio.h>' or provide a declaration of 'fprintf'
I'm not able to reproduce this but someone should check and see if it still affects 9999
Assuming fixed, I do not see any implicit-function-declaration warnings in later versions
