| Subject: [PATCH] configure.ac: fix implicit function declaration in mail spool |
| directory check |
| |
| Fixes the following error with Clang 15 (which makes implicit function |
| declarations an error by default): |
| ``` |
| +error: call to undeclared library function 'exit' with type 'void (int) __attribute__((noreturn))'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] |
| exit(0); |
| ^ |
| note: include the header <stdlib.h> or explicitly provide a declaration for 'exit' |
| ``` |
