* fclose: pacify gcc -Wanalyzer-file-leakPaul Eggert2023-04-241-0/+13
| | | | | | | | | | | | | | 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.

(configure.ac): Replace fopen when replacing fclose.
