Ripping out the Asserts surely can't take long.

No, the reason for write_stderr() is that fprintf(stderr) is unreliable
on Windows. If memory serves, it can actually crash in some situations.
More generally, it's not very clear what to do with error reports in an
OS environment where stderr isn't a universally supported concept.
So (IMO anyway) you can't just ignore the problem. And it's not one
that's going to be solved in five minutes, either.
