Ok, I understand. This would cover the needed references for
functions defined in LY_DEFINE and friends, but would not
address the other standard C++ style references that are
found by the etags program.  I am very reluctant to attempt
to re-implement in LilyPond something that available in the
existing utility.  And, if I add -ddump-tags to lilypond, the
make system will still need to be adapted to merging the two
sources of TAG references.

I have a merge request prepared that implements
'make TAGS' using the existing lilypond makefile system.
It does rely on a single python script to mangle the C++
identifiers.

Jean, David, Jonas,  Unless one of you tell me not to do so,
I will submit it as is for review and consider Jean's
suggestion as a pre-planned improvement.
