OK, I have removed the boolean, and just #ifdef'ed the LOAD_FUNCPTR
macros. The problem is that if initscr is a macro, typeof(initscr) may
not do what we want, so we can't use MAKE_FUNCPTR(initscr).
I also made a define for the name of the library, so the error messages
say the "curses" not "ncurses" if curses is used.
