- Subject: [patch] fix libssp on darwin
Two part patch here. The first fixes -fstack-protector-all to link in
the ssp libraries, the second links in the files at all on darwin.
Probably fairly obvious, but I'll ask for confirmation.
Tested on ppc-darwin with ssp enabled, make all and building a couple
of small programs. Currently having issues bootstrapping with the
support turned on by default due to the changes jakub made when
pulling libssp out into it's own directory and --enable-bootstrap not
working :(
OK?
