I have written a plain Perl code library file, that can calculate a
32-bit CRC of a string, if that may be of any use. It can easily be
adapted to calculate a cumulative CRC over multiple strings, for if the
file's too big.

I adapted it from some C source code. It gives the same results as the
compiled C program (on PC) for the tests that I have done.

Of course, it'll be rather slow on large strings, compared to compiled
C. Also, note that there are more than one definition of "CRC", so I
can't garantee compatibility.

I can mail it to you if you want it. That goes for anybody else as well.
It's fun to play with. :-)
