+Subject: [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-complain.h (generic_fatal, fatal_syntax, fatal_sys)
+* src/b-fb.h (Ierror, Oerror)
+* src/base.h (unexpected_EOF, thank_you_and_goodnight):
+Move ‘exiting’ attribute to beginning of func decl.
