This is interesting. Do you have a link to their reply? I'd like to
see what they had to say, and if they have an explanation for this.

this is simple enough that it should probably done, yeah. (though I
dislike working around compiler bugs).

Well, as far as I understand how names clashes are supposed to be
avoided, the compiler should define and use symbols that start with

I'll see what I can do about mcount.
