Have you tried compiling it with "cc -DBACKWARD -o check_crc check_crc.c"??
The program contains the following message in the opening comments:
 *
 * To compile, first try
 *      cc -o check_crc check_crc.c
 * if that fails your machine is not MINIX/POSIX compatible so try:
 *      cc -DBACKWARD -o check_crc check_crc.c
 *

There are also other compatibility  issues for any program... To wit: I could
compile check_crc.c on a Sun Sparc (but only with -DBACKWARD), but it always
crashed with a Bus Error.  I eventually tracked this down to a call to
sscanf().  I have included my fix for this, along with a code change to 
make the output line up a little better.

This is my own change,  and is not an official fix; but if you have been 
having trouble getting it to work on a Sparc, this should help...
