This is a question about the GNU binutils, not about gcc. I recommend taking any followup to binutils@xxxxxxxxxxxxxxx See http://sourceware.org/binutils/ . The answer is that -e does not imply -u, although that is likely to change in the next binutils release. Most systems link against crt0.o explicitly. Ian
