Power C! I grew up in Germany and after the inevitable BASIC, C was the second language I learned, using Power C as a compiler, which I ordered by mail and which arrived from the States several weeks later, including the hard copy reference manual you mention. I also remember it came with a rudimentary graphics library I used to create screen savers for friends. Good times.
