lynx does not build with ncurses-6.1

[Pierre Labastie]

You get:

make[1]: Entering directory '/sources/lynx/lynx2-8-8/src'
Compiling Lynx sources
gcc -DHAVE_CONFIG_H  -DLOCALEDIR=\"/usr/share/locale\" -I. -I.. -Ichrtrans -I./chrtrans -I.. -I../src -I.././WWW/Library/Implementation    -D_GNU_SOURCE  -DLINUX -D_GNU_SOURCE -D_DEFAULT_SOURCE -O2  -c LYStrings.c
LYStrings.c: In function 'expand_tiname':
LYStrings.c:1011:14: error: dereferencing pointer to incomplete type 'TERMINAL {aka struct term}'
  if (cur_term->type.Strings[code] != 0) {
              ^~

The reason is that the type "TERMINAL" is now opaque. This is fixed upstream (at lynx2.8.9.dev.12).
