Thank you; however, I'm having problems with libstdc++ tests.

I downloaded from svn the trunk:

However, the libstdc++ tests failed:

Could you give me some hint on how to correct this?
I did do all the steps outlined here:

  http://gcc.gnu.org/contribute.html#testing

i.e.

    make clean-target-libstdc++-v3                    # clean libstdc++ and ...
    test -d */libjava && make -C */libjava clean-nat  # ... parts of libjava
    make all-target-libstdc++-v3 all-target-libjava   # rebuild compiler and
libraries
    make -k check-c++                                 # run C++/libstdc++
testsuite


So, I've no idea how to proceed.

Any help would be appreciated.

TIA.
-Larry
