+ add test-packages for cross-compiling ncurses-examples using the
MinGW test-packages. These are only the Debian packages; RPM later.
+ cleanup format of debian/copyright files
+ add pc-files to the MinGW cross-compiling test-packages.
+ correct a couple of places in gen-pkgconfig.in to handle renaming of
the tinfo library.
+ modify_nc_flush() to retry if interrupted (patch by Stian Skjelstad).
+ change map files to make _nc_freeall a global, since it may be used
via the Ada95 binding when checking for memory leaks.
+ improve sed script used in 20141220 to account for wide-, threaded-
variations in ABI 6.
+ fix an uninitialized variable in -c/-n logic for infocmp changes
(cf: 20120526).
+ corrected fix for building c++ binding with clang 3.0 (report/patch
by Richard Yao, Gentoo #417613, cf: 20110409)
+ correct configure check for working poll, fixing the case where stdin
is redirected, e.g., in rpm/dpkg builds (Debian #676461).
+ add rpm- and dpkg-scripts, to test those build-environments.
The resulting packages are used only for testing.
