From: Marcos Paulo de Souza <mpdesouza@xxxxxxxx>
When compiling with clang, this warning is shown:
common/utils.c:404:3: warning: declaration does not declare anything [-Wmissing-declarations]
__attribute__ ((fallthrough));
This attribute seems to silence the same warning in GCC. Changing this
attribute with /* fallthrough */ fixes the warning for both gcc and
clang.
