Do you have /dev/pts mounted?  Without it dejagnu does not work
properly and generate lots of errors.

There should be test-summary.gz in /usr/share/doc/gcc-3.4 (or
just test-summary in the build directory) with an overview of
what the status of the tests.

This for instance lists this for C on i386:
                === gcc Summary ===

# of expected passes            24999
# of unexpected failures        2
# of expected failures          70
# of untested testcases         7
# of unsupported tests          201
/home/packages/gcc/3.4/gcc-3.4-3.4.3/build/gcc/xgcc version 3.4.4
20041218 (prerelease) (Debian 3.4.3-6)


And this for c++:
                === g++ Summary ===

# of expected passes            9769
# of unexpected successes       3
# of expected failures          71
# of unsupported tests          43
/home/packages/gcc/3.4/gcc-3.4-3.4.3/build/gcc/testsuite/../g++
version 3.4.4 20041218 (prerelease) (Debian 3.4.3-6)


So for C there are 2 unexpected failures and for C++ there are 3
unexpected successes.  I wouldn't call that many errors.  I could
only hope that it gives as good as results as this on all arches.
