Hi,
For a week or so, AOUT library of -current is broken.
"make -DWANT_AOUT world" fails at the following point:

__main.o: Undefined symbol `___do_global_ctors' referenced from text segment
*** Error code 1
-------- log ends here ---------
This error occurs because ___do_global_ctors does not exists in libgcc.a.
So, I think the following patch will be needed for -current.

Since -mno-486 option of gcc is deleted, the following patch also needed
for "make -DWANT_AOUT world".
