libstdc++ with gcc 4.9 on ubuntu 15.10

[Peter Steinbach]

Hi - 

I am the developer of a CUDA library and the users recently reported a bug for 
ubuntu 15.10. As CUDA currently does not support gcc 5.*, I have to compile all 
host binaries with gcc-4.9. The funny thing, my build system bails out with the 
following error message when linking to libboost_unit_test_framework which I 
was able to reproduce with the attached source code:

$ gcc-4.9 -D_GLIBCXX_USE_CXX11_ABI=0 external_main_example_1.cpp 
-lboost_unit_test_framework
tmp/ccDk5v3M.o: In function 
`boost::unit_test::make_test_case(boost::unit_test::callback0<boost::unit_test::ut_detail::unused>
 const&, boost::unit_test::basic_cstring<char const>)':
external_main_example_1.cpp:(.text._ZN5boost9unit_test14make_test_caseERKNS0_9callback0INS0_9ut_detail6unusedEEENS0_13basic_cstringIKcEE[_ZN5boost9unit_test14make_test_caseERKNS0_9callback0INS0_9ut_detail6unusedEEENS0_13basic_cstringIKcEE]+0x42):
 undefined reference to 
`boost::unit_test::ut_detail::normalize_test_case_name(boost::unit_test::basic_cstring<char
 const>)'
collect2: error: ld returned 1 exit status

The above follows the recommendations from 
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html. Note that, 
if I build boost with gcc 4.9 on 15.10, the above works as expected.

I was wondering if this is a known feature of the ubuntu boost distro? Are 
there any workarounds to this, that I potentially overlooked?

Best,
Peter
