This sounds OK. However, i have still a single error on Cygwin, it is for AT 
136 "Tabulations and multibyte characters".

The reason is that wchar_t is 16-bit on this platform (i.e. Windows), therefore 
several of the (multibyte) characters in this test
do not fit. See 
https://lists.gnu.org/archive/html/bug-bison/2019-11/msg00011.html for the 
exact results of this test.

I suggest to SKIP this test in case the number of bits in wchar_t is not 32 
(see BITSIZEOF_WCHAR_T). Indeed, since the
mbrtowc() and related functions are used, characters using 4 UTF-8 bytes cannot 
be handled properly.

Thanks in advance.
