Hi,
Avahi 0.6.18 fails to build on several archs out of the box (that is without disabling stack
protection), because stack protection is enabled even though gcc reports it's unsupported.
The most interesting bit from the config.log is the following:
configure:4989: checking whether gcc accepts -fstack-protector
configure:5017: gcc -c -g -O2 -fstack-protector conftest.c >&5
conftest.c:1: warning: -fstack-protector not supported for this target
configure:5023: $? = 0
configure:5040: result: yes
configure:5063: checking whether g++ accepts -fstack-protector
configure:5091: g++ -c -g -O2 -fstack-protector conftest.cpp >&5
conftest.cpp:1: warning: -fstack-protector not supported for this target
configure:5097: $? = 0
configure:5114: result: yes
Simplest fix would be to run the checks with -Werror
