After reading the Xref node and glancing at the "Creating Tags Tables"

the TAGS files. Then I visited a C file in the src directory and tried
'M-.' on an identifier. The result was the error message 'Symbol’s

That sounds like a bug. Did you try it in the current version in the
branch emacs-25? I fixed something like that not too long ago (though
more than a week ago, for sure).
