-    [C slog] Move ‘exiting’ to beginning of func decl.
-    
-    Apparently, ‘gcc --std=c11’ does not abide the ‘exiting’
-    attribute appearing at the end of the func decl.
-    Reported by Romain Francoise.
-    See also <https://bugs.debian.org/778100>.

-    * src/b-fb.h (Ierror, Oerror)
-    * src/base.h (unexpected_EOF, thank_you_and_goodnight):
-    Move ‘exiting’ attribute to beginning of func decl.
