Image Processing in C: Analyzing and Enhancing Digital Images with 3.5 Disk

Hi. My name is Don. I read the Image Processing in C by Dwayne Phillips. He said that the source code is compiled using Microsoft C v6.0. I asked some stores they said that they had not see Microsoft C v6.0 before. Therefore, could you check again for me, please? If he knows any store is selling it, please send me a address or email of store. Thank you very much. I am waiting your rely. Sincerely, Don.
