It turned out to be a problem with DMD. It had declared a type as 
"unsigned int" instead of "size_t". stat.st_size appears to be 64bit in 
the iPhone simulator SDK.

Then I got a new problem. When I compile druntime it complains about 
conflicting module names. Somehow it seems the package name disappears.

Yes, just as you can, I assume, with the compilers already present in 
<path>/iPhoneSimulator.platform.

I was planning to try and run a D program in the iPhone simulator. As a 
first step, I thought it would be much easier then running it on the 
real device. The simulator runs 32bit code and not ARM.

If we eventual can run D program on iOS devices I'm pretty sure we also 
want to run them on the simulator.

Can't hurt to try and see what it takes :)
