I installed the patch below, which should fix that.

Sorry, I don't know C++ namespaces that well, but I'll guess that this
is because the Tru64 C++ compiler doesn't conform to the latest C++
standard.  The easiest fix for me is to check that "std:cerr" works,
and to reject the C++ compiler otherwise.  I hope the patch below
accomplishes that.

Thanks for reporting these problems.

        Fix some "make check" problems with C++ reported by
        Albert Chin-A-Young for Tru64 C++ in this thread:
        http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html

        * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
        * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
        Output to a .cc file for C++, not to a .c file.
        * tests/calc.at (AT_CHECK_CALC): Likewise.
        * tests/regression.at (AT_CHECK_DANCER): Likewise.
        * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
