[BUG] The configure.ac file fails guessing OS when on darwin

[jgabaut]

ATM, the configure.ac file fails capturing the guessed OS given by config.guess.

This is because config.guess responds with darwinX.Y.Z, but the checks in configure.ac are only looking for darwin specifically.

A quick patch would look like this:

diff --git a/configure.ac b/configure.ac

   AC_SUBST([HELAPORDO_CFLAGS], ["-I/opt/homebrew/opt/ncurses/include -DKOLISEO_HAS_CURSES"])

But a better fix would not peg the version number, thus refactoring the checks to expect darwin* for a macOS build.

• OS: macOS
