It seems like gdb_curses.h is included whenever we want to access ncurses functionality, instead of including directly ncurses.h. As a result, clangd often erroneously shows that gdb_curses.h inclusions are unused. By adding those pragmas, clangd (and the include-what-you-use tool) understands that gdb_curses.h is a valid provider for whatever these ncurses.h files provide.
