For those you specify which 'as' and 'ld' to use - how else do you think they work. I don't think you configured your GCC properly if you cannot get it to use some binutils from /usr/ports. In fact when installing GCC on Solaris GCC strongly prefers (or use to) gas and gld to Sun's as and ld. Just tweak that configure logic. -- -- David (obrien@FreeBSD.org)
