+
+2004-05-30  Albert Chin-A-Young  <china@thewrittenword.com>
+
+       Don't assume the C++ compiler takes the same arguments as the C compiler
+       (trivial change).
+       * configure.ac (O0CXXFLAGS): New var.
+       * tests/atlocal.in (CXXFLAGS): Use it.

+
+       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.

+
+       Spent a few hours checking out which prerequisite versions the
+       current sources actually require.  I went all the way back to
+       Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+       a seemingly endless set of combinations of versions more recent
+       than that.  The bottom line is that the current sources require
+       fairly recent versions of the build tools, and it'll be some work
+       to change this.
+       * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+       (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+       (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+       Add comments explaining why those particular versions are
+       currently needed.
+       
+       * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+       in SGI MIPSpro 7.4.1m.  Problem reported by Albert Chin-A-Young in
+       <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+       * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+       (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
 2004-05-26  Paul Eggert  <eggert@cs.ucla.edu>
 
        * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
