Thomas E. Dickey 47d2fb4537 ncurses 6.2 - patch 20200212
+ update release notes
+ minor build-fixes, mostly to test-package scripts
+ modify check for sizeof(wchar_t) to ensure it gives useful result
  when cross-compiling.
+ drop assumption in configure script that Cygwin's linker is broken.
+ define NCURSES_BROKEN_LINKER if the broken-linker feature is used,
  to simplify configure-checks for ncurses-examples.
+ reassert copyright on ncurses, per discussion in ncurses FAQ:
  https://invisible-island.net/ncurses/ncurses.faq.html#relicensed
+ modify comparison in make_hash.c to correct a special case in
  collision handling for Caps-hpux11
+ add testing utility report_hashing to check hash-tables used for
  terminfo and termcap names.
+ fix a missing prototype for _nc_free_and_exit().
+ update a few comments about tack 1.07
+ use an awk script to split too-long pathnames used in Ada95 sample
  programs for explain.txt
