+    _Static_assert needs two arguments for compatibility with GCC before 9
+    
+    This macro definition enforces two arguments even with newer compilers
+    that accept the single-argument form, too.

+    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.
