Fix 2025/jhshrvdp to include curses.h instead of ncurses.h; Ncurses

[SirWumpus]

supports curses.h as an alternative name and for backwards compatibility.

Sigh 😞

Landon will correct me if I'm wrong but I could have sworn (from Landon himself) that it's important to match the library with the header file i.e. if you use -lncurses you need to use ncurses.h and if you use -lcurses you need to use curses.h.

We went through this issue before with NetBSD not having ncurses (think that was it) but it probably was never resolved fully.

But with this one if -lcurses works perhaps the Makefile should be updated: assuming that I am correct (iirc Landon said it was a subtle point)?

I have never seen a problem incidentally with this but I guess Landon might have or knows of such problems.

if you use -lncurses you need to use ncurses.h and if you use -lcurses you need to use curses.h.

For the 2025 winning entry in question, it can use either.
