Patchset looks good from the code layer though it is a bit complicate
in 2/3 stringify handling, but that should be acceptable.

My only hesitating is about ##__VA_ARGS__, because it says that is still
as GNU's extension but have not got into standard C.

So I especially run with GitHub CI and got pretty compiling results, then I
have
a positive attitude on applying these patches unless there is someone who
blames it broken something in a general (but I guess the possibility is
very little).
