Thanks, I guessed so but was not sure.

At least I can not see that it works.

What I was trying to say was this (that it probably are conditioned for X)
and that it is a problem because with
    #ifdef HAVE_X_WINDOWS
around hourglass activation/deactivation you can only get things working on

For the w32 port there are also
    #if 0
around the body part of the functions that do the actual job
(start_hourglass, hide_hourglass), since it is (as far as I understand) not
implemented on w32 yet.

I suggest removing the "#ifdef HAVE_X_WINDOWS" completely or (which I
believe most would like better - but not I) replacing them with something

    #ifdef HAS_HOURGLASS

Can we please do one of these so that it is possible to implement hourglass
