Fix examples

Allow menu_scroll.d to compile on 64-bit platforms....though it won't run because of what looks to be a bug in mvwaddch()
EDIT: s/bug in mvwaddch()/bug with ACS properties/ Not sure what exactly, yet.
EDIT 2: I just remembered, this still doesn't build because the ACS.FOO don't work.  ACS_FOO _will_, but screws up my terminal while bailing with a range violation.
