Typing `C-c` (*SIGINT*) in a *screen* session (Debian package 4.0.3-14; -11 is
fine):
* shell prompt: no reaction (nothing printed)
* `sleep 10` running: `^C` printed, but SIGINT is not sent.

Revisit this issue: [[!debbug 97343]] -- special handling of `TIOCSCTTY`
depending on `__GNU__`.

`#ifdef linux` and friends are used in quite a number of places.

TODO: check: `HAVE_SVR4_PTYS` is due to `configure.in` doing `test -c
/dev/ptmx`. But: even if we don't have that file, we still have `ptsname`,
`grantpt`, `unlockpt`.
