Paul Eggert 506ffb1f74 (YYSTACK_ALLOC_MAXIMUM): New macro. 
(YYSIZE_T): Define to unsigned long int when using an older compiler.
(yyparse): Revamp code to generate long syntax error message, to
make it easier to translate, and to avoid problems with arithmetic
overflow.  Change "virtual memory" to "memory" in diagnostic, since
we don't know whether the memory is virtual.

Paul Eggert 1ce590705a * NEWS: Bison-generated C parsers now use the _ macro to 
translate strings.
* data/yacc.c (_) [!defined _]: New macro.
All English strings wrapped inside this macro.
* doc/bison.texinfo (Bison Parser): Document _.
* po/POTFILES.in: Include src/parse-gram.c, since it now
includes translateable strings that parse-gram.y doesn't.

Paul Eggert d7e14fc000 * NEWS: Bison-generated parsers no longer default to using the

to widespread problems in unchecked stack-overflow detection.

responsibility to set it to a positive value.  This lets the user
specify a value that is not a preprocessor constant.

Also, explain the constraints on YYINITDEPTH.
