    builder: Suppress warning about unused yyunput.
    
      CC       virt_index_validate-index-validate.o
    index-scan.c:1270:17: warning: 'yyunput' defined but not used [-Wunused-function]
         static void yyunput (int c, register char * yy_bp )
                     ^
      CCLD     virt-index-validate
    
    By using %option nounput we can prevent this from being generated in
    the first place.
