curses problem under AIX 3.1 (3001 and 3002)

[Peter Blemel]

   Unfortunately I do not know if there is some fixed standard for curses,
but RT AIX, SunOS, BSD 4.3, and most other OS's that I have used initialize 
stdscr->_y to be a batch of blanks (after appropriate setup calls). The
curses library for AIX 3.1 leaves this pointer nil, which is a major
source of heartburn for most packages that I need to port. inch() will
crash the program because of this, as does overwrite(). Is there some
standard auxiliary call that needs to be made (that is a freebie on these
other systems) ?

Thanks,
Peter
