The one thing the MS C compiler seemed good at was compiling gigantic "translitered" functions (generated by a code translator of the company where I was working at the time). Otherwise, meh.
Turbo Pascal for Windows was simply awesome, (unfairly) compared to the C SDK for Windows 3.X, as well. The windowing library (objects), and the way it linked methods as event callbacks were much easier to read and write than hand-crufted event loops/switches in C. MS eventually made something comparable in C++, but I was long gone to *nix land by the time that mattered.
>Bill Gates saw the success of Turbo Pascal "in very personal terms, and 'couldn't understand why [Microsoft's] stuff was so slow. He would bring in poor Greg Whitten [programming director of Microsoft languages] and yell at him for half an hour.' He couldn't understand why Kahn had been able to beat an established competitor like Microsoft."
It's certainly possible that someone was using TurboPascal (discontinued mid 90s) at same time as VisualC or the early version of MS C.
