ncurses 5.9 - patch 20140726

+ eliminate some redundant -I options used for building libraries, and
  ensure that ${srcdir} is added to the include-options (prompted by
  discussion with Paul Gilmartin).
+ modify configure script to work with Minix3.2
+ add form library extension O_DYNAMIC_JUSTIFY option which can be
  used to override the different treatment of justification for static
  versus dynamic fields (adapted from patch by Leon Winter).
+ add a null pointer check in test/edit_field.c (report/analysis by
  Leon Winter, cf: 20130608).
