I did:
> + set_binary_mode (STDOUT_FILENO, O_BINARY);
Oops, that produces a compilation error (reported by the 'grep' CI and
the 'sed' CI):
../../gltests/test-dfa-match-aux.c: In function ‘main’:
../../gltests/test-dfa-match-aux.c:61:20: error: ‘STDOUT_FILENO’ undeclared
(first use in this function)
61 | set_binary_mode (STDOUT_FILENO, O_BINARY);
| ^~~~~~~~~~~~~
Fixed like this:
2023-04-25 Bruno Haible <br...@clisp.org>
dfa tests: Fix compilation error (regression 2023-04-22).
