Subject: poll: Check if _REDIR_TIME64 is defined
|
|
|
|
Treat _REDIR_TIME64 being undefined like being set to 0.
|
|
|
|
This fixes the following compile error in strace:
|
|
```
|
|
In file included from pathtrace.c:12:
|
|
/include/fortify/poll.h:46:30: error: "_REDIR_TIME64" is not defined, evaluates to 0 [-Werror=undef]
|
|
46 | #if defined(_GNU_SOURCE) && !_REDIR_TIME64
|
|
| ^~~~~~~~~~~~~
|
|
cc1: all warnings being treated as errors
|
|
```
