* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
Use a diversion to avoid outputting comments etc.
Removes 17k lines from testsuite (10% of the number of lines).
* tests/local.at (AT_COMPILE, AT_COMPILE_CXX): If OUTPUT ends with ".o",
then append the "natural" extension for the input file (.c or .cc).
If there is no source, pass -c.
* tests/headers.at, tests/input.at, tests/regression.at: Adjust.
* tests/local.at (AT_NAME_PREFIX): Take api.prefix into account.
(AT_API_PREFIX): Rename as...
(AT_API_prefix): this.
Do not take %name-prefix into account.
Fix misuses.
* tests/local.at (AT_LEX_FORMALS, AT_LEX_ARGS, AT_LEX_PRE_FORMALS)
(AT_LEX_PRE_ARGS): Rename as...
(AT_YYLEX_FORMALS, AT_YYLEX_ARGS, AT_YYLEX_PRE_FORMALS)
(AT_YYLEX_PRE_ARGS): these, for consistency.
(AT_API_PREFIX): Take %name-prefix into account.
(AT_YYLEX_PROTOTYPE): New.
Use it.
* tests/actions.at, tests/calc.at, tests/cxx-type.at: Adjust to
use them.
* tests/local.at (AT_YYERROR_PROTOTYPE): New.
Use it.
* tests/cxx-type.at: Extensive revamp to use a more traditional
quotation scheme, and to use the generic yyerror implementation.
Prefer Autotest macros to CPP macros.
* tests/java.at: .
* tests/local.at (AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE)
(AT_YYERROR_DEFINE): Handle locations for C and C++.
* tests/calc.at: Use it for C++ (as C has extra arguments which
are not yet handled by AT_BISON_OPTION_PUSHDEFS).
* tests/actions.at: Adjust.
* tests/local.at (AT_LANG): Use c++ instead of cxx for C++.
Adjust dependencies.
(AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE): Issue nothing
for C++/Java.

(AT_JAVA_COMPILE): Use AT_SKIP_IF.
Using http://github.com/lyda/misspell-check, massage its
output into sed commands to perform the suggested changes.
Initially, I filtered out the THRU->Through changes, because
that failed to retain capitalization in the grammar token.
Instead, do this manually, beforehand:
sed -i s/THRU/THROUGH/ tests/existing.at
git ls-files|misspellings -f -|perl -nl \
-e '/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/ or next;' \
-e '($file,$n,$l,$r)=($1,$2,$3,$4); $q="'\''"; $r=~s/$q/$q\\$q$q/g;'\
-e 'print "sed -i $q${n}s!$l!$r!$q $file"'|bash
Currently the test 248, "parse-gram.y: LALR = IELR", fails
BISON_TEST_XML is set.
* tests/local.at (AT_BISON_CHECK_XML): Belt: Save/restore files.
* tests/regression.at (parse-gram.y: LALR = IELR): Suspenders: Don't
rely on expout.
Each one of these changes suffices.
Some of our macros play with expout and other Autotest special files,
which may break their callers (e.g., currently TESTSUITEFLAGS='248
BISON_TEST_XML=1' fails).
There is already some support for this. Expand it to be ready to use
it elsewhere.
* tests/local.at (AT_RESTORE_SPECIAL_FILES, AT_SAVE_SPECIAL_FILES)
(at_save_special_files, at_restore_special_files): New.
(AT_BISON_CHECK_NO_XML): Use them.
The Hydra buildfarm provides code coverage analysis. For some reason,
in some test cases, code coverage data seem to be incompatible, and
generate error messages at parser run-time. Ignore these messages so
that (i) these tests do pass, (ii) coverage results be provided by
Hydra.
* tests/local.at (AT_PARSER_CHECK): Ignore messages for failed merges
of code coverage/profiling results.
* tests/local.at: Go for colors.
(--compile-c-with-cxx): New option.
We used to pass "CC=$CXX" as command line argument,
but it was not possible to adjust CFLAGS accordingly
in atlocal, since it is loaded before assignments on
the command line are honored (so that the command line
takes precedence).
* tests/atlocal.in: Implement it.
* tests/local.mk: Use it.

drop the unexpected token unless there actually is no lookahead.
Moreover, handle that internally instead of returning 1 to tell
the caller to do it. With that meaning of 1 gone, renumber

Fix stale comments.
Bison developers should use GNU M4 and should not use
POSIXLY_CORRECT when building the test suite, so do not
complicate the code by avoiding $10 and above.
Do not quote an empty string value for an optional argument, and
do not distinguish between a missing value and an empty string
value.
