There is a lot of them. I understand your concern. However we do not have to
do anything difficult to use HAVE_HOURGLASS. After taking a look at the code
I believe HAVE_HOURGLASS should go into src\config.in. There is already an
#ifdef HAVE_X_WINDOWS and I suggest putting something like this after that
define:

   /* This is for the hourglass code in various files. */
   #if defined(HAVE_X_WINDOWS) || defined(HAVE_NTGUI)
   #define HAVE_HOURGLASS
   #endif

IMO it will be more readable and if you want to add hourglass code for other
systems some day it is easier.
