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'
