It seems like a fairly trivial change.

However, it is not adequate to simply make a variable to control this,
as the decision whether to actually use XIM would then have to be made
before creating the first frame, so setting that variable to "don't
use XIM" too late will not have any effect.

The proper solution is probably to make a function to enable/disable XIM on
an X display; as I see it, the use of XIM is actually per-display, so this
would be more flexible than the current compile-time constant.
