Details

Minimal breaking example (example.y):

$ bison example.y
$ gcc example.tab.c -ly
/usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.2/../../../../lib/liby.a(yyerror.o): In function `yyerror':
(.text+0x12): undefined reference to `rpl_fprintf'
collect2: ld returned 1 exit status

Expected behaviour: not that.

If yyerror is defined, rather than the liby one used, no such error occurs.

Downgrading to Bison 2.4.3 "fixes" this problem.
