Thanks.
I'm adding a signature test. (So far, we have a signature test for these
functions only in C++ mode, in tests/test-unistd-c++.cc.)
2024-05-15 Bruno Haible <br...@clisp.org>
getusershell tests: Verify the function declarations.
* tests/test-getusershell.c: Include signature.h.
(getusershell, setusershell, endusershell): Check the signatures.
* modules/getusershell-tests (Files): Add tests/signature.h.
