Ignore last message, I ran the calc++ example without ./configure && make.
But now I get the following error, with extra quotes in the #line directives.
They do not appear if I compile the same example with bison 3.0.5. So it seems
to be a bug in the pre-release.
$ make
../../src/bison -o parser.cc parser.yy
g++ -c -ocalc++.o calc++.cc
g++ -c -odriver.o driver.cc
g++ -c -oparser.o parser.cc
parser.cc:334:10: error: """parser" is not a valid filename
#line 42 ""parser.yy"" // lalr1.cc:635
^~~~~~~~
parser.cc:341:10: error: """parser" is not a valid filename
#line 42 ""parser.yy"" // lalr1.cc:635
