That was a fun read. Just until recently, I also worked on a code base that originated in Think C/68k, albeit in the order of several hundred thousand lines of code. It was quite the effort when I had to take it through Apple's transitions, porting it to OS X/Carbon/Codewarrior, then to Xcode/gcc/UTF-8, then to Intel, finally lifting the whole thing to Cocoa/64 bit/clang. We even had prototypes on iOS. The Windows version remained largely unchanged despite being ported to Unicode and 64 bits. Microsoft is doing a crazy good job at keeping APIs alive.
