And include the new, split out version in drivers/keyboard.c and drivers/usb/usbhid.c. Those files were including curses.h just for those definitions, but the include path was only fixed up to to point to the libpayload versions of those files if one of the variants of curses was compiled in. If neither was, gcc would fall back to the system version of that header which is wrong.
