I didn't intend _that_.

I did intend this change (which appears to be "all" that I did):

    + updated ".map" files to reflect move of comp_captab and comp_hash
      from tic-library to tinfo-library in 20090711 (report by Sven
      Joachim).

I did that change by adding an entry to a table which I setup to ensure
that "_nc_" entrypoints needed by tack continue to be global.  That,
and regenerating the ".sym" files (to drop local symbols) should have
been the only changes.

well, then I'll go back to working on my script.  (It takes about an hour
to run through all of the builds needed to record the information, so it's
slow to investigate).
