New description:

 See this:
 http://git.bind10.isc.org/~tester/builder/BIND10/20120723120000-FreeBSD8-i386-Clang/logs/build.out
 and
 http://git.bind10.isc.org/~tester/builder/BIND10/20120724134032-Solaris11-i386-GCC/logs/build.out

 Regarding the first one: From experiments offset_ptr in some older
 versions of boost causes this error on clang++.  Confirmed with boost
 1.43 + clang 2.8 and boost 1.42 + clang 3.1, so it's more about the
 boost version and doesn't depend on the clang version.

 Regarding the second one: it turned out the failing system installed
 boost via pkgsrc, which installs its own boost/config/user.hpp, which
 caused this error.

 Maybe these are minor cases, but it's probably helpful to detect this in
 ./configure and tell the user to upgrade boost.  It should suffice to
 check it with AC_TRY_COMPILE() using this test code:

 {{{#!cpp
 #include <boost/interprocess/offset_ptr.hpp>
 }}}
 (Note: for the second one we need -Werror because technically it's not
 an "error", but a warning then converted to an error due to -Werror)

 Also: we should not just writing the check code in configure.ac, but
 figure out how exactly these errors happen, especially for the second
 one.
