    All failures in the libc++ test suite will be documented here.

    Last run was with Clang (pre-3.1) and GCC 4.6.3 (with dw2 exception handling) and
     mingw-w64 v2.0.3 on i686-w64-mingw32.

    The following line was added to ./lib/buildit to make a static libc++ library because a DLL requires "declspec(dllexport)" or a .def file:
    ar rcs libc++.a *.o
    I also deleted libc++.dll and libc++.dll.a to make sure libc++ was linked statically to prevent unrelated issues from contaminating the test results.
    The commands to build and test were (-nodefaultlibs does not work, lots of MinGW related stuff gets left out resulting in linker failures):
    TRIPLE=i686-w64-mingw32 ./buildit
    TRIPLE=i686-w64-mingw32 HEADER_INCLUDE="-I/home/Ruben/libcxx/include" LIBS="-L/home/ruben/libcxx/lib -lc++ -lpthread -lsupc++ -lmsvcr100 -Wl,--allow-multiple-definition" ./testit > test.log 2>&1

    Note: Some locale tests may "Need investigating", but I think most problems are
          caused by wrong/unportable locale naming in the tests.
    Note: Some tests failed to link because "test.exe" was still running when ld.exe
          tried to link the next test. I left these failures out of the list; they
          account for about 10-30 failures, and are counted in the total scores below.
          I reran some of these failures manually and they passed.
    Note: Some tests fail at runtime but pass when run manually. Usage of std::cout
          segfaults so further investigation is difficult. These also contribute to
          the failures total, but are left out of the failure list, as the cause is
          probably not located in that part of libc++, not locatable due to the lack
          of usable debug info generated by Clang at this time.

    TOTAL RESULTS:
    Section failures / total sections: 104 / 1064 = 9.8% failures
    Test failures / total number of tests: 292 / 4326 = 6.7% failures
