rl_set_screen_size() is declared in rlprivate.h.  It is not supposed to
be an external entry point; that's why it is not exported in the dll. 
It is defined in terminal.c but is not marked 'static' there, presumably
because other, internal-to-readline functions call it -- but that
non-static designation means that is is exposed in the static library
and in unix shared librarys.  Just not dll's.  However, I can't find
*any* other reference to that function, other than the two I just
mentioned.  So, exteranl apps are not supposed to use
rl_set_screen_size(), and readline itself never calls the function.  I
think rl_set_screen_size() is dead code.

What package are you compiling that wants 'rl_set_screen_size()" ?
