Bob answered this already, but if you have GNU binutils nm, you can
compare the difference of `nm' and `nm --demangle' of the objects
created in this test.  I assume g++ uses the same mangling on darwin, so
that would be:
  a2(char)
This function is used in libb, and also in a template in the b.hh header
which is instantiated in main().

I wrote the test with different link lines to find out what is portable
and what is not.  If you comment out the AT_CHECKs below the comments
  # lib convenience
and 
  # both installed
(both of these do not link libb.la against liba.la), does the test
succeed then?  If so, could you commit a patch doing this for host_os
darwin?  (I would still like to test this for other systems, even if our
link lines are not portable, it provides nice information.  Maybe add a
comment to this extent.)

Oh, if above does not work, I would not mind an
  AT_XFAIL_IF(test "X$host_os" = ...)
in tests/template.at.
