Whitesmiths C compiler: One of the earliest commercial C compilers available

That brings back some memories from my early days. I worked on a project that had decided to use the newish C language for a 68000-based system. They chose Whitesmith compiler for it, probably because it was the only one available. For some reason, I was selected to attend a class on learning C and became responsible for installing the compiler and assisting the other engineers on using it. The project was ultimately successful but I don't recall what issues we had with it. I do remember contacting Whitesmith a couple of times to resolve some problems. I guess it possible I was talking directly to P.J. Plauger himself, although, at that time, I would have had no idea who he was.
