| Subject: [PATCH] configure: Add correct system headers and prototypes to tests |
| |
| Newer compilers e.g. clang-15+ have turned stricter towards these |
| warnings and turned them into errors which results in subtle failures |
| during build, therefore make the testcases use the needed headers and |
| modern C |
