You shouldn't show the mouse pointer to anything other than the
screen of a subbitmap of the screen -- I can't see any reason
to, anyway.  If you're doing something like blitting the bitmap
to the screen, you'll get problems if the mouse cursor moves
while you blit, so you want to either hide it (not helpful) or
freeze it.  But you might as well draw your own pointer -- since
it'll only be displayed when you blit, there's not much point in
having it move around.

Showing mouse on memory bitmap might not work correctly, if bitmap
size is larger than screen and mouse range is set to this size.  In
such cases you can try to add a call to get_mouse_mickeys somewhere
in a loop, so it is called at least once per second.  Then mouse
handler will be switched in different mode and mouse should be able to
move anywhere in the bitmap.

It's different -- it's specified in DJGPP.ENV.  You can do it in
the environment too though, and your path will get included too:

    set C_INCLUDE_PATH=...

I'm not sure whether the C include path is the correct one to
use, but it probably is.

Michael Bukin is working on the X port; I'm not, I've only
worked on the Linux console port.
