Yes, I can confirm it, this bug exists (not only for Ubuntu). Today, I
use two temp. "solutions", either

i. I do not make 'cxxsup' test at all

  % make -s tests IGNORE_LINK_ERRORS=y ;# only 1 test cannot be built!

or

ii. I have installed GCC-4.3 *in parallel*

  % sudo aptitude install gcc-4.3 g++-4.3 ;# this won't ruin your box

and with that GCC I can build all tests

  % make -s CC=gcc-4.3 && make -s CC=gcc-4.3 tests ;# all should pass
