ncurses 5.9 - patch 20120225

+ modify configure script to allow creating dll's for MinGW when
  cross-compiling.
+ add --enable-string-hacks option to control whether strlcat and
  strlcpy may be used.  The same issue applies to OpenBSD's warnings
  about snprintf, noting that this function is weakly standardized.
+ add configure checks for strlcat, strlcpy and snprintf, to help
  reduce bogus warnings with OpenBSD builds.
+ build-fix for OpenBSD 4.9 to supply consistent intptr_t declaration
  (cf:20111231)
+ update config.guess, config.sub
