Msys2 fails

[Schmeckinger]

Problems I encountered so far with this lib.
Msys2 ncurses is a bit different.
It needs #include<ncurses/ncurses.h>, or #include<ncursesw/ncurses.h>
And the deltion of the test binary doesn't work, because .exe is missing.

let bin = format!("{}", Path::new(&out_dir).join("chtype_size").display());

needs to be:

let bin = format!("{}", Path::new(&out_dir).join("chtype_size.exe").display());
