Considering that I don't think that self-building with -fstack-protector will ever be common, I don't think we ought to spend too many brain cells on this. The only way to bootstrap with -fstack-protector without existing support in libc is to use a top-level bootstrap. That said, I don't think this really addresses what you want to accomplish... > I am interested in doing this so that I can have a > libgfortran built with -fstack-protector to try to track down > a potential stack corruption problem. Thanks in advance for any > advice. This should be as simple as make all-gcc make all-target-libssp make CFLAGS_FOR_TARGET='-O -g -fstack-protector-all' all-target-libgfortran and then explicitly build your test program with -fstack-protector-all so that the right libraries get linked in. r~
