The reason you can't find is because universal ctags, etc, by default
disable detecting some stuff. Per this question
https://stackoverflow.com/q/3655743/2388257#when-using-exuberant-ctags-what-options-to-you-use
you can use e.g.
$ ctags --c-kinds=+defgpstux -R .
then, with universal ctags, I see the tag.
