4. BFD problem--"Undefined symbol _aout_32_swap_exec_header_in".
+Believed to be fixed (fix not yet tested with GDB).
5. The linker complains about mfree and so on being multiply defined.

link. I haven't investigated, but probably just another easy

not. This could be done by getting paperwork from CMU and merging
