+	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.
+
 2004-05-28  Albert Chin-A-Young  <china@thewrittenword.com>
 
 	* tests/calc.at, tests/actions.at: Workaround for SGI
