* expm1 tests: Avoid test failure on 32-bit mingw.Bruno Haible2023-04-262-5/+6
| | | | * tests/test-expm1.h (test_function): Mark y as 'volatile'.
* poll tests: Avoid test failure on native Windows.Bruno Haible2023-04-253-2/+10
| | | | | | | * tests/test-poll.c (test_pipe): Disable the POLLHUP check also on native Windows. * doc/posix-functions/poll.texi: Mention also native Windows w.r.t. POLLHUP.
* dfa tests: Fix compilation error (regression 2023-04-22).Bruno Haible2023-04-253-0/+8

* fclose: pacify gcc -Wanalyzer-file-leakPaul Eggert2023-04-243-0/+23
| | | | | | | | | | | | | | Without this patch, building coreutils with --enable-gcc-checking=expensive would fail with a message like “lib/exclude.c:682:6: error: leak of FILE 'in' [CWE-775] [-Werror=analyzer-file-leak]”, because Gnulib replaced fclose but not fopen, and GCC saw a call to fopen followed by a call to rpl_fclose. The patch causes GCC to instead see a call to rpl_fopen followed by rpl_fclose. * m4/fclose.m4 (gl_FUNC_FCLOSE): Replace fopen when replacing fclose. * modules/fclose (Depends-on): Add fopen. (configure.ac): Replace fopen when replacing fclose.
