According to http://msdn.microsoft.com/en-us/library/ff798083.aspx core.stdc.stdio._iob should have a size of 20, but we have it at 60. Is that because the Digital Mars C runtime differs, or is it incorrect?

But it says that IOB_ENTRIES is 20, and _iob is an array of FILE with IOB_ENTRIES elements. So it completely depends on MSVC's layout of FILE, which almost definitely doesn't match DMC's.

Huh, I misunderstood...you were getting at the actual IOB_ENTRIES value.

No idea, sorry. :( But my guess is that DMC just differs in some way.
