Gerbil macOS ncurses FFI

Running brew info ncurses gives us the following part:

Gerbil ncurses FFI macOS

So, I am a little bit (very) new to C, "systems programming" and the tools surrounding C. I thought it would be fun to try to make a little ncurses thing with Gerbil!

I've installed gcc version 12.3.0 (with Nix if that matters) and ncurses6 with Homebrew. This would be instead of using clang provided by macOS by default? I think I read in the docs that gcc is preferred. Is this still the case on macOS?

I've compiled a C-program using ncurses with gcc and got it to run using the following:

gcc `ncurses6-config --cflags --libs` test.c -o test.out
