I have created a package tape & 'fixed' source tape for Hack 1.0.3 for 4.2 BSD. gcc is required to compile the source, pcc chokes when trying to build. I have made minor modifications to the source with regards to some variables, and renaming variables called 'inline'..
If the COMPAT_42 is built with any later BSD it should run the binary otherwise producing your own ought to be trivial.
The modified source is here:
