Subject: [PATCH] configure: avoid compiler warning in pipe2 detection
|
||
|
|
|
||
|
|
When building qemu-kvm for openSUSE:Factory, I am getting a
|
||
|
|
warning in the pipe2 detection performed by configure, which
|
||
|
|
prevents using --enable-werror.
|
||
|
|
|
||
|
|
Change detection code to use return value of pipe2.
