98a1045bea CI: check on PPC64le, ARM64 and s390x 
I was hoping it would help us catch warnings when char is
unsigned (see 78bb152a63), but it does
not seem to help.  It's a pity that the compiler is the same all over
the place, I would have preferred testing others.

* .travis.yml: here.

7122d747cf yacc.c: no longer support YYERROR_VERBOSE 
Supporting YYERROR_VERBOSE via cpp is a nuisance: m4 is in charge of
handling alternatives.  When adding more options for %define
parse.error, supporting both CPP and M4 is too complex.  Anyway,
YYERROR_VERBOSE was deprecated long ago.

* data/skeletons/yacc.c: Use m4 only to handle verbose/simple error
messages.

f983d00e77 yacc: restructure and fix yysyntax_error 
I would like to offer new ways to build the error message.  As a first
step, let's simplify yysyntax_error whose first loop does two things
at the same time: (i) collect the tokens to be reported in the error
message, and (ii) accumulate their sizes and possibly return
"overflow".  Let's pull (ii) in a second step.

Then test 525 (regression.at:1193: parse.error=verbose overflow)
failed.  This test checks that we correctly report "memory overflow"
when the error message is too large.  However the test is mistaken: it
is triggered in a place where there are five (large) expected tokens,
so anyway we would not display them, so there is no (memory) overflow
here!  Transform this test to (i) check that indeed there is no
overflow, and (ii) create syntax_error3 which does check the intended
behavior, but with four expected tokens.

* data/skeletons/yacc.c (yysyntax_error): First compute the list of
arguments, then compute yysize.
* tests/regression.at (parse.error=verbose overflow): Enhance and fix.

78bb152a63 tests: also check -Wchar-subscripts 
GCC's -Wchar-subscripts may report issues on platforms where char is
unsigned.  Unfortunately the current CI does not reproduce the
problem.  But that would allow contributors to report issues if the
warning appears somewhere.

See 139d065594.

* configure.ac (warn_common): Add -Wchar-subscripts.
