ncurses 5.9 - patch 20120218

+ correct CF_ETIP_DEFINES configure macro, making it exit properly on
  the first success (patch by Pierre Labastie).
+ improve configure macro CF_MKSTEMP by moving existence-check for
  mkstemp out of the AC_TRY_RUN, to help with cross-compiles.
+ improve configure macro CF_FUNC_POLL from luit changes to detect
  broken implementations, e.g., with Mac OS X.
+ add configure option --with-tparm-arg
+ build-fix for MinGW cross-compiling, so that make_hash does not
  depend on TTY definition (cf: 20111008).
