32-bit 循环冗余校验的 C和PASCAL 应用程序

Changes to version 1.0:

        The algorithm used to calculate the initial CRC matrix has been 
optimized to run in logarithmic time instead of linear time, the practical 
upshot of which is that calculations that previously took up to a minute now 
take less than two seconds.

        Supporting C and Turbo Pascal code has been modified to support DOS 
versions below 3.0.
