rhbz1504009: let dtrace -G -o /dev/null run, as in autoconf
|
|
|
fae7c94 |
|
|
|
fae7c94 |
commit c245153ca193c471a8c broke the ability of dtrace to be tested in
|
|
|
fae7c94 |
autoconf "-G -o /dev/null" usage, because its output file name was too
|
|
|
fae7c94 |
simple a function of the input name, and normal users can't write to
|
|
|
fae7c94 |
/dev/null.dtrace-temp.c . Now we back down to mkstemp, like before,
|
|
|
fae7c94 |
upon a failure of the simple concatenated name.
