but _nc_handle_sigwinc() body is in ncurses/tty/lib_tstp.c which does not seem 
to be linked into libtinfo.so.X while libtinfo wants to use it.

address@hidden ~/rpm/BUILD/ncurses-5.5]$ objdump 
-t ./obj-narrowc/lib/libncurses.so.5.5 | grep _nc_handle_sigwinch
00000000000122a0 g     F .text  000000000000006e              
_nc_handle_sigwinch

address@hidden ~/rpm/BUILD/ncurses-5.5]$ objdump 
-t ./obj-narrowc/lib/libtinfo.so.5.5 | grep _nc_handle_sigwinch
0000000000000000         *UND*  0000000000000000              
_nc_handle_sigwinch

existing ncurses copy shouldn't have any meaning here
