misc/libreoffice fails to build

[Paul Goyette <paul%whooppee.com@localhost>]

With up-to-date pkgsrc (including recend updates to libvisio and libcdr) 
I am unable to build libreoffice.  There are hundreds of error messages 
in the log file, starting with

[build CXX] sal/osl/unx/file_error_transl.cxx

And then a whole lot of BOOST-related messages:

/tmp/pkgs/misc/libreoffice/work.x86_64/.buildlink/include/boost/type_traits/is_nothrow_move_constructible.hpp:30:96: warning: "BOOST_GCC_VERSION_WORKAROUND_GUARD" is not defined [-Wundef]
 #elif !defined(BOOST_NO_CXX11_NOEXCEPT) && !defined(BOOST_NO_SFINAE_EXPR) && !BOOST_WORKAROUND(BOOST_GCC_VERSION, < 40800)

                ^
/tmp/pkgs/misc/libreoffice/work.x86_64/.buildlink/include/boost/config/workaround.hpp:244:10: note: in definition of macro 'BOOST_WORKAROUND'
        ((symbol ## _WORKAROUND_GUARD + 0 == 0) &&     \
          ^~~~~~

Followed by some regex-related issues?

/tmp/pkgs/misc/libreoffice/work.x86_64/libreoffice-6.0.3.2/opencl/source/openclconfig.cxx: In function 'bool {anonymous}::match(const rtl::OUString&, const rtl::OUString&)':

(I can provide the entire build log if needed - it's about 260kb)
