Can someone point me to a reference that talks about this? -N is a linker option. The documentation, such as it is, is here: http://sources.redhat.com/binutils/docs-2.12/ld.info/Options.html#Options If you pass -N to gcc when doing a link, gcc will pass -N on to the linker. As far as I know this behaviour is undocumented. Ian
