Build problem on amd64 (cs/test_crc.cs failes) - patch included

Hello,

the code in cs/ does not pass it's testsuite on amd64 machines, at least not 
on mine and a quick search on the net confirmed that others have the problem 
too.

The crc32 result is assigned to a long field and therfore does not "wrap 
around" (get negative).

I was able to solve this issue by explicitly casting the ne_crc()-result to 
INT32 (as typedef'ed in neo_misc.h) when assigned to result->n (a long 
field).

The code compiles and runs just fine and passes the testsuite.

The simple patch:

    }
    if (val.alloc) free(val.s);
    return STATUS_OK;

If there is a problem with this I don't see, please comment so that I can 
search for another solution.
