Actually, thinking clearly, it's a huge input text points file it needs. 
So it was easy to create a random one to test it with. And it turns out as 
well as the conditionalised ftello(), it also needs
#define USE_LARGEFILES 1
right at the start of the file to "activate" the Largefile support in 
config.h. But after that r.in.xyz works fine and reports the percentage 
progress correctly. I'm not sure if this is by design or by accident that 
it works like this but it's quite neat really.

If we get this hammered out properly it can go on
