Yes, I had this identical problem: it IS 4.2! I got 4.2 and superimposed
it onto a SLS 0.99, together with a pl 1 kernel, and pointed libc.so.4
to it, and login broke exactly in the way you describe.
Quickest fix: make a symbolic link /lib/libc.so.O, point it to the
libc.so.4.1 library; emacs /bin/login, Ctrl-S for libc.so.4, change the 4
into an O, and save it. Now it works again.
Note that you CANNOT patch with perl, since it truncates input files at
first binary byte of 0 (the little fix for this perl bug has also been
posted in a followup to my msg, if you have perl sources to patch).
