>Description:

$() parsing is still broken in bash 4.0.33 as installed by the port.

We need to pass the -y flag to bison.  Plain "bison -d parse.y"
outputs parse.tab.c instead of y.tab.c, so y.tab.c is never
regenerated, and the parser fix from patch 001 is effectively not
applied.

[Resent as PR so it doesn't get lost again.]

>How-To-Repeat:

bash -c 'echo $(echo \|)'
