[TUHS] SVR4 x86 -- Sources

[Nick Downing]

Yes, but I think the SunOS 4 shared library stuff was based on a.out,
I remember looking at the ld.so source code and thinking how simple
and elegant it all was, until those SysV people got their hands on it
and created ELF ;)  What SysV release introduced ELF though?
cheers, Nick
