Paul Eggert 3ea5f0ec81 * bootstrap: Add stdio-safer, unistd-safer modules. 
Remove m4/glibc2.m4 (introduced by latest gnulib, but
we don't need it).
* lib/.cvsignore: Add dup-safer.c, fd-safer.c,
fopen-safer.c, stdio-safer.h, unistd-safer.h.
* lib/subpipe.c: Include "unistd-safer.h".
(create_subpipe): Make sure all the newly-created
file descriptors are > 2, so that diagnostics don't
get sent down them (which might cause Bison to hang, in theory).
* m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
* src/files.c (xfopen): Use fopen_safer, not fopen.

Paul Eggert 51c30d2144 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port 
yesterday's yacc.c fix.

Paul Eggert cea1469d47 Fix a destructor bug reported by Wolfgang Spraul in 
<http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
* data/yacc.c (yyabortlab): Don't call destructor, and
don't set yychar to EMPTY.
(yyoverflowlab): Don't call destructor.
(yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
* tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
since we no longer output the message "discarding lookahead token
end of input ()".

Paul Eggert 80ce3401e9 * tests/actions.at: Test that stack overflow invokes destructors. 
From Marcus Holland-Moritz.
* data/yacc.c (yyerrlab): Move the code that destroys the stack
from here....
(yyreturn): to here.  That way, destructors are called properly
even if the stack overflows, or the user calls YYACCEPT or
YYABORT.  Stack-overflow problem reported by Marcus Holland-Moritz.
(yyoverflowlab): Destroy the lookahead.

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.
