Comment:

 And this is the proposed changelog entry:
 {{{
   144.? [build]         jinmei
         Introduced a workaround for clang++ build on FreeBSD (and probably
         some other OSes).  If building BIND 10 fails with clang++ due to
         a link error about "__dso_handle", try again from the configure
         script with CXX_LIBTOOL_LDFLAGS=-L/usr/lib (the path actually
         doesn't matter; the important part is the -L flag).  This
         workaround is not automatically enabled as it's difficult to
         detect the need for it dynamically, and must be enabled via the
         variable by hand.
         Another unrelated note about clang++ on FreeBSD: the build may
         fail in compiling a test.  If that happens try disabling compiler
         optimization by setting CXXFLAGS manually. (Trac #474, svn rTBD)
 }}}

 As noted above, we need to disable compiler optimization to build it on
 freebsd8-32-1-on-virt1 (e.g., by CXXFLAGS=-g).

 The only offending file is ccsession_unittests.cc.  I've not figured it
 why (yet), maybe it's too complicated?  In any case if we want to solve it
 this should go to a separate ticket.
