Subject: [PATCH 75/81] Apply asm redirections in syslog.h before first use [BZ
|
|
#27087]
|
|
|
|
Similar to d0fa09a770, but for syslog.h when _FORTIFY_SOURCE > 0.
|
|
Fixes [BZ #27087] by applying long double-related asm redirections
|
|
before using functions in bits/syslog.h.
|
|
|
|
Tested with build-many-glibcs.py.
