autofs-5.1.3 - update configure to check for pipe2(2)
|
|
|
306fa1 |
|
|
|
306fa1 |
In a bug report by John Salmon it appears that the use of __have_pipe2
|
|
|
306fa1 |
isn't doing what's needed when checking for pipe2(2).
|
|
|
306fa1 |
|
|
|
306fa1 |
Hopefully updating configure to explicity check for pipe2(2), lifted
|
|
|
306fa1 |
from John's patch, will be more reliable.
