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.
