I think the "(including some C17)" bit would not make much sense
anymore. There were no major changes in C17 and GCC implements
`-std=c11` and `-std=c17` as basically the same thing according to the
docs (and GNU extensions apply equally to both, I would assume).

When I wrote the "(including some C99 features)" I meant that GCC
implemented some C99 features as extensions in C90 mode, and the
kernel used some of those (e.g. the now gone VLAs).

With that changed, for `programming-language.rst`:
