 Hmm... These symbols are generated by gcc when -fstack-protector is in
 effect. It is usually disabled by default but lang/gcc46 has a patch
 to (eventually) enable it by default for some reason.
 
 These ssp symbols usually reside in libc (/usr/lib/libSystem.B.dylib
 in this case) but MacOS X < 10.5 doesn't provide them. GCC provides
 its own implementation (libssp) for such platforms but it isn't used
 in the bootstrap phase.
 
 As I have no boxes with MacOS X 10.4 installed, I want you to try the
 following:
 
   1. bmake clean; bmake patch
 
   2. Open work/gcc-4.6.4/gcc/common.opt with your favorite editor.
 
   3. Replace line 1793:
 
        Common Report Var(flag_stack_protect, 1) Init(-1)
 
      with:
 
        Common Report Var(flag_stack_protect, 1)
 
   4. Run bmake and see what happens.
 
 
 Thanks,
