lib_bkgd.c demands WINDOW._bkgd

[Robert Joop]

[ncurses 5.2 patch 20011218]

the compiler tells me

../ncurses/./base/lib_bkgd.c: In function `wbkgrndset':
../ncurses/./base/lib_bkgd.c:75: structure has no member named `_bkgd'

the line reads

            win->_bkgd = ((tmp == EOF) ? ' ' : (chtype) tmp) | AttrOf(wch);

win is a WINDOW *, i've found

include/curses.h:typedef struct _win_st WINDOW;
include/curses.h:struct _win_st

but struct _win_st doesn't contain any _bkgd member, the compiler is of
course right.
it contains a _bkgrnd member, but it's of an incompatible type.

i've no idea what the fix should be...
