b327f38832 deprecate %defines in favor of %header 
This is consistent with --defines being deprecated in favor of
--header.  The directive %defines is also too similar to %define.
And %header matches nicely with api.header.name.

* src/scan-gram.l (%defines): Deprecate to %header.
(%header): Scan it.
* src/parse-gram.y (PERCENT_DEFINES): Replace with...
(PERCENT_HEADER): this.

c483b6593f tests: refactor the handling of Perl 
Let's make a difference between places where Perl is required for the
test (AT_PERL_REQUIRE), and the places where it's used to run the
test, but it's not not to run the test (AT_PERL_CHECK).

* tests/local.at (AT_REQUIRE): New.
(AT_PERL_CHECK, AT_PERL_REQUIRE): New.
Use them where appropriate.

* tests/local.mk ($(TESTSUITE)): Beware not to start the line with
'-pi' if Perl is empty, as Make understands this as "it's ok to fail".
Which it is not.

0c56c195e0 tests: be really robust to Perl missing 
My previous tests (with ./configure PERL=false) have been fooled by
configure, that managed to find perl anyway.  This time, I ran this on

* tests/input.at, tests/local.at, tests/named-refs.at,
* tests/output.at, tests/regression.at, tests/skeletons.at,

1161649446 preserve the indentation in the ouput 
Preserve the actions' initial indentation.  For instance, on

    | %define api.value.type {int}
    | %%
    | exp: exp '/' exp { if ($3)
    |                     $$ = $1 + $3;
    |                   else
    |                     $$ = 0; }

we used to generate

    |     { if (yyvsp[0])
    |                     yyval = yyvsp[-2] + yyvsp[0];
    |                   else
    |                    yyval = 0; }

now we produce

    |                  { if (yyvsp[0])
    |                     yyval = yyvsp[-2] + yyvsp[0];
    |                   else
    |                     yyval = 0; }

Currently, with --no-lines, instead of "#line file line\n", we emit
"\n".  Let's emit nothing.

* data/skeletons/bison.m4, data/skeletons/c.m4, data/skeletons/glr.cc,

27630864e7 build: work around ICC's limitations

adf0425d11 escape properly the file names in #line for printer/destructor 
Reported by Jannick.
http://lists.gnu.org/archive/html/bug-bison/2017-05/msg00001.html

"Amusingly" enough, we have the same problem with %defines when the

an incorrect C string.

* src/output.c (prepare_symbol_definitions): Escape properly the file
names before passing them to M4.
* data/bison.m4, data/lalr1.cc: Don't simply put the file name between
two quotes (that should have been strong enough a smell...), expect
the string to be properly quoted.

827bc59ca1 %union: fix the support for named %union 
Bison supports a union tag, for obscure reasons.  But it does a poor
job at it, especially since Bison 3.0.
Reported by Stephen Cameron and Tobias Frost.

It did not ensure that the name was not given several times.  An easy
way to do this is to make the %union tag be handled as a %define
variable, as they cannot be defined several times.

Since Bison 3.0, the synclines were wrongly placed, resulting in
invalid code.  Addressing this issue, because of the way the union tag
was stored (as a code muscle), would have been tedious.  Unless we
rather define the %union tag as a %percent variable, whose synclines
are easier to manipulate.

So replace the b4_union_name muscle by the api.value.union.name
%define variable, document, and check.

* data/bison.m4: Make sure that api.value.union.name has a keyword value.
* data/c++.m4: Make sure that api.value.union.name is not defined.
* data/c.m4 (b4_union_name): No longer use it, use api.value.union.name.
* doc/bison.texi (%define Summary): Document it.
* src/parse-gram.y (union_name): No longer define b4_uion_name, but
api.value.union.name.
* tests/input.at (Redefined %union name): New.
* tests/synclines.at (%union name syncline): New.
* tests/types.at: Check named %unions.

5422d56a71 tests: add -pedantic for --enable-gcc-warnings. 
This should help to avoid some portability problems.  For example,
it would have revealed the empty unions fixed by the last patch
* configure.ac (WARN_CFLAGS_TESTS, WARN_CXXFLAGS_TEST): Implement.
* tests/synclines.at (AT_TEST_SYNCLINE): Avoid -pedantic warning
about an empty translation unit.
