Hi Marcus, I've just rechecked the "-e" option, and it works fine for me. I'm wonderwed why (and how) it didn't work for you.
I hope I already answered your questions and you see the needness of this patch. So I hope you agree that I'll commit it tomorrow (with comments about compiler options) Thanks.
