Apparently the version of mingw import libraries that come with GNAT 3.15p
is too old and does not include the definition of SetCursorPos.

I would suggest using either an update import library for the Windows libraries,
or updating to a newer version of GNAT.

We will see if this reference can be removed from GtkAda to avoid this
problem.
