What do you mean for FSF assignment form?

Yes, I saw a piece of collect2 code that generate an export file. It seems that
all global ctrs/dtrs are exported correctly. But for shared object we need
to export all global symbols. I'll try to understand how I can differ these
symbols in collect2 object parsing process - so, it may take a little time.

I have not played with exception handling yet - so, I don't know what symbols
must be exported except __eh_*.
