commit e6fb95871cd3557e5882a6f969c11bc6a3cbe781
Author: Florian Weimer <fweimer@redhat.com>

Turn on -Werror=implicit-function-declaration
GCC 4.4, the minimum compiler version, supports this option. Unlike
other warnings, -Wimplicit-function-declaration warnings should be
independent of compiler versions, so this change should not cause
compiler-specific build failures.
