GCC's cpp was exiting when it failed to find requested includes
(<ncurses_cfg.h> and <ncurses_defs.h>). clang-cpp just silently
ignored the missing header files (thus not honoring any macros
defined in those).

This is a regression introduced earlier this year in an ncurses upgrade when this was switched to using CPP + CPPFLAGS (which is always empty) instead of CC + CFLAGS (which the other generated files still use?). The fact that clang-cpp silently fails and ignores errors seems like a bug in clang-cpp to me.
