The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it. It still does with fprintf.
Also, s/cstdio.h/cstdio/.

Sparc, as they were causing more porting problems than the
(minor) performance improvement was worth.
and if we are not debugging. POSIX requires this.
* NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.
* src/output.c (output_gram, output_rule_data): Do not assume that
the user defines YYDEBUG to a properly parenthesized expression.
otherwise, since we range over their symbols, we might look at a
nonterminal which no longer ``exists'', i.e., it is not counted in
`nvars', hence we overflow our arrays.
RHS's properly.
* tests/torture.at (GNU AWK Grammar): New.
* tests/sets.at (Nullable): New.
* src/nullable.c (set_nullable): Instead of blindly looping over
`ritems', loop over the rules, and then over their rhs's.
Work around Autotest bugs.
* src/warshall.c (bitmatrix_print): Don't use `+--+' as table
frame, because Autotest understand lines starting with a `+' as
traces from the shell. Then, they are not processed properly.
Admittedly an Autotest bug, but we don't have time to wait for
Autotest to catch up.
* tests/regression.at (Broken Closure): Adjust to the new table
frames.
Move to...
* tests/sets.at: here.
Do not infringe on the global user namespace when using C++.
(YYFPRINTF, YYSTDERR): New macros, needed for the above.
All uses of `fprintf' and `stderr' changed.
* src/output.c (output): Do not output "#include <stdio.h>"; that
is bison.simple's job. stdio.h should be included only if
necessary, to avoid infringing on the user name space when
possible.
Reported by Pascal Bart.
* src/warshall.c (bitmatrix_print): New.
(TC): Use it.
When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
j must be the outer loop.
* tests/regression.at (Broken Closure): New.
removal of useless rules via CPP but via `if (0)', so that the
compiler still check the code is valid.
For instance, it should have noticed `rline' no longer exists: use
the `line' member of rule_t.
* src/gram.c (dummy, rline): Remove, unused.
items of a state, not only its kernel.
* src/print.c (print_core): If `trace_flag', then invoke closure
before outputting the items of the state (print_core is no longer
a correct name them).
(print_results): Invoke new_closure/free_closure if needed.

argument, as it is replaced by the results by the unique caller.
(build_relations): Merely invoke transpose: it handles the memory
deallocation.
Improve variable locality.
Avoid variables used as mere abbreviations.
(compute_lookaheads): Use arrays instead of pointers.
