I've `gcc-10 (Ubuntu 10.1.0-2ubuntu1~18.04) 10.1.0` and I'm afraid, thats not
enough. I've tried to compile it with following:
/usr/bin/gcc-10 -D_FORTIFY_SOURCE=2 -I/opt/devel/openwrt/testing/include -g -Os
-ggdb -Wextra -Wall -Werror --std=gnu99 -Wmissing-declarations
-Wno-unused-parameter -fstack-protector-strong -Wformat -Werror=format-security
-o CMakeFiles/umdns.dir/service.c.o -c
/opt/devel/openwrt/c-projects/mdnsd/service.c
which "just" yields following errors in service.c:
service.c:110:10: error: comparison of integer expressions of different
signedness: ‘int’ and ‘long unsigned int’ [-Werror=sign-compare]
service.c:279:16: error: comparison of integer expressions of different
signedness: ‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Werror=sign-compare]
