Looking at the download page, I'm thinking that was before they had installers. Is the download just a server jar, ready to run?

[denizkoekden]

There is no jar in these old versions. You have to copy the content of the downloaded zip (e.g. forge-1.4.7-6.6.1.528-universal.zip) into the minecraft_server.jar file. You can check if the forge version needs to get installed like this if the contents of the zip-file is a lot of .class-Files.

Oh, I remember doing that whole thing. OK, this is becoming an enhancement, not a bug. Quite doable but not trivial.
