causing more problems than it was curing, since it didn't work
properly on some nonstandard C++ compilers. This can wait
for a proper C++ parser.
* NEWS: Document this.
* doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
of C++, as it's treated like C now.
* src/bison.simple (YYSTD): Remove.
(YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
Treat C++ just like Standard C instead of trying to support
namespace cleanliness.
YYDEBUG must be defined to a nonzero value.
* src/bison.simple (yytname): Do not assume that the user defines
YYDEBUG to a properly parenthesized expression.
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.
* doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
(YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
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.
to be the same as the stack names.
(yyparse): yyptr is now union yyalloc *, not char *.
(YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
and may generate better code on some machines.
(YYPOINTER): Remove.

(YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
and may generate better code on some machines.
(YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
(YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
New macros.
(union yyalloc): New type.
(__yy_memcpy): Last arg is size_t, not unsigned int, to remove
an arbitrary restriction on hosts where size_t is wider than int.
(yyparse): Don't dump core if alloca or malloc fails; instead, report
a parser stack overflow. Allocate just one block of memory for all
three stacks, instead of allocating three blocks; this typically is
faster and reduces fragmentation.
Do not limit the number of items in the stack to a value that fits
in 'int', as this is an arbitrary limit on hosts with 64-bit
size_t and 32-bit int.
