+ some build-fixes for ncurses-examples with NetBSD-6.0 curses, though it lacks some common functions such as use_env() which is not yet addressed. + build-fix and some compiler warning fixes for ncurses-examples with OpenBSD 5.3 + fix a possible null-pointer reference in a trace message from newterm. + quiet a few warnings from NetBSD 6.0 namespace pollution by nonstandard popcount() function in standard strings.h header. + ignore g++ 4.2.1 warnings for "-Weffc++" in c++/cursesmain.cc + fix a few overlooked places for --enable-string-hacks option.
