GCC doesn't like a direct cast from a pointer to an integer of
different size. This is what I'm doing, basically double-casting the
pointer to a 64 bit integer, and thence to a 32 bit value:
--- newcloud.cxx 30 May 2005 09:04:57 -0000 1.8
+++ newcloud.cxx 11 Aug 2005 03:56:51 -0000

pauseLength = 0.0f;
last_step = -1.0f;
familly = CLFamilly_nn;
- cloudId = (int) this;
+ cloudId = (int)(long)this;
sgSetVec3(center, 0.0f, 0.0f, 0.0f);
sgSetVec3(cloudpos, 0.0f, 0.0f, 0.0f);
radius = 0.0f;
There is a similar spot in FlightGear where something wants to use a
pointer as an integer "ID". I haven't checked these in as this is not
really a good solution -- the ID needs to be guaranteed-unique.
