fb554c2804 m4: fix b4_token_format 
We used to emit:

    /** Token number,to be returned by the scanner.  */
    static final int NUM = 258;
    /** Token number,to be returned by the scanner.  */
    static final int NEG = 259;

with no space after the comma.  Fix that.

* data/skeletons/bison.m4 (b4_token_format): Quote where appropriate.

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.
Problem reported by Andy Fiddaman in:
https://lists.gnu.org/r/bug-bison/2019-12/msg00021.html

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

d4a6c3c58a c++: beware of short ranges for state numbers 
Now that we use small integral types, possibly unsigned (e.g.,
unsigned char), to store state numbers, using -1 to denote an empty
state (i.e., a state that stores no semantical value) is very
dangerous: it will be confused with state 255, which might be
non-empty.

Rather than allocating a larger range of state numbers to keep the
empty-state apart, let's use the number of a state known to store no
value.  The initial state, numbered 0, seems to fit perfectly the job.

Reported by Frank Heckenbach.
