Enabling it still results in:
rc4test[14703]: segfault at 00007fffe457e70c rip 0000000000403447 rsp 00007fff0453e2b8 error 4
make[2]: *** [test_rc4] Segmentation fault

And I can't change it from CHAR to INT without breaking ABI.  Either
someone needs to write a version that works with CHAR, or you'll
have to wait until I need to change the soname, like a 0.9.9 release.
