When libncurses is configured with gpm support and gpm with ncurses support,
libncurses.so depends on libgpm.so and libgpm.so depends on libncurses.so.
Such loops should never happen.
If Gpm_Wgetch is passed non-NULL win argument, it must have been created by
ncurses anyway and so it should be already loaded.
On the other side, if Gpm_Wgetch is never used or used just with
NULL argument, libncurses is never needed.
