| Subject: [PATCH] configure.ac: fix __xmknod{,at} pointer argument |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| Switch default to assume * and not the absence of *. |
| |
| On glibc 2.33+, there is no definition for these functions in header |
| files, so the compile test doesn't work. But, we can default to using |
| the pointer (as is the case with newer glibc), and use the header file |
| on older platforms to fail the test and use no pointer. |
