You did nothing wrong.  

libg++'s CursesW.cc and the BSD curses library are incompatible.
CursesW has to grope around in the curses WINDOW struct, but for
whatever reason BSD curses decided to rename some of the fields.

We hacked the CursesW.cc in the (older) libg++ that's in the NetBSD
source tree to refer to the new BSD curses names.  In hindsight, what
we should have renamed those fields back to their original names.
