I was programming on MacOS (the original) since it was possible. I remember many of these error messages! Especially "Too many errors on one line (make fewer)".

...also remember 45 minute builds when a header file changed.

In those days I wrote exclusively system extensions, plug-ins and XCMDs, using a mix of 68k, C and Pascal. Each project was quite small, so compile time was never a problem and MPW was a paradise. My largest XCMD actually had bits in all 3 languages which MPW happily linked together, and some projects had various little blocks of code to stick in the same file, all of which could be automated easily.

I remember these error messages coming up and laughing out loud when I saw the rare ones. Nice work, whoever did it!
