The fact that imenu doesn't understand special macros is one out of
three aspects I listed (BTW, etags also handles SYSCALL, ENTRY, PSEUDO).
Why did you ignore the remaining ones?

Probably.  But the problem of matches within comments and strings is
more difficult to handle and much more annoying for other sources.  The
most serious problem with using imenu for change-log entries, on the
other hand, is its inability to cleanly report variable and macro
definitions.  With other words: What `add-log-current-defun' gets me is
usually a subset of what etags finds.  It considerably differs from what
imenu reports.
