+Subject: [PATCH] Replace YYUSE call with void cast in src/parser.y
+
+The YYUSE macro was renamed to YY_USE in bison 3.7.5; we might as well
+avoid using it altogether and cast the unused variable to void instead.
+
+Fixes the following linker error:
+
+/usr/bin/ld: kafel/libkafel.a(libkafel.o): in function `kafel_yyerror':
+arm_syscalls.c:(.text+0x6984): undefined reference to `YYUSE'
