Looks like it only happens on targets where open is not LFS ready (unlike *BSD).

Confirmed with mainline (20031107) on RedHat 9. Is this practical to support, or should we just 
add this as a known limitation.

I doubt it is practical to support this.

Would you please explain why you doubt that is practical to support files larger 
than 2GB?

It is OK for an Ada implementation to have capacity limits. In this case the limits are caused by the 
underlying OS, the corresponding C library functions have the same limitation. Indeed, it would be nice 
to remove this limitation by using the appropriate new C library functions on targets where needed/
supported, but this clearly is an enhancement request.
