ncursesw-morphos/test/test_inwstr.c
Thomas E. Dickey 92e187a345 ncurses 5.7 - patch 20100501
+ correct limit-check in wredrawln, accounting for begy/begx values
  (patch by David Benjamin).
+ fix most compiler warnings from clang.
+ amend build-fix for OpenSolaris, to ensure that a system header is
  included in curses.h before testing feature symbols, since they
  may be defined by that route.
