OK Macro Interference

[Geoffrey Viola]

Hi,

I had some issues with include order due to macro definitions in the ncurses header file. I noticed that ncurses defines an OK macros and leaves it defined in https://github.com/mirror/ncurses/blob/a7e05fb9806cc1255b6ba4fb29e15d337f35b2ad/include/curses.h.in#L371. This causes some issues for functions that may want to be called OK: https://github.com/ApolloAuto/apollo/blob/master/cyber/state.h#L43. Would it be possible to change OK to NCURSES_OK? Another option that would work for me would be to undefine the OK macro outside of curses.h. Also, should the other macros follow? For example, there's TRUE, FALSE, and ERR.
