Wow.  Facinating.  

I understand now.  gcov measures coverage of whatever code is executed.
We write the tests (you obviously used the unit tests), and it shows
which code was exercised.  Can that URL be automatically updated?  

I looked at the dblib coverage.  A lot of the not-covered code is error
code, like returning FAIL if dbproc == NULL.  I would say it would be a
waste of time to write a test to make sure every function fails that
way.  But there are functions and functionality that are never touched.
Looking at bcp.c, I see my own predilections e.g. no test for text and
data or native mode.  Scripting a test with freebcp would help.  

Nice work.  Thanks.
