Subject: [PATCH] configure.ac: fix __xmknod{,at} pointer argument
|
||||||
|
|
||||||
|
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.
