well - looks like there's only a few possible ways to improve:

a) supposing that if the symbol versions (not the symbols) for "ncurseswt"
   and "ncursest" version changed (by a configure option of course) to
   make them distinct from the symbol versions in "ncursesw"/"ncurses",
   then you could find out whether the linker is able to properly resolve
   two sets of symbol versions for the same symbols (I suspect that it is
b) link everything against "ncurseswt"
