  Or upstream should add an explicit --tag=CC, or rename the file extension.
Good catch, that certainly ties in with what that link I found was saying.

  Hmm, there are two harfbuzzes, one old, one new; one has .cc files, the
other .cpp files.  It appears that they both do actually use C++ features, but
perhaps in a limited way; as long as they don't throw exceptions or use RTTI
or any of the standard C++ library functions, they could not need linking
against libstdc at all.  In that case maybe upstream's solution would be to
add "-fno-exceptions -fno-rtti" to the CXXFLAGS and "--tag=CC" to the LDFLAGS.
 Don't know which code base the distro package is based on though; let's wait
and see what Yaakov has to say.

    cheers,
