That's a somewhat different problem.
1.7.9-jumbo-5 (as opposed to -jumbo-6) lacks its own sha512crypt
support. Thus, it only supports these hashes when running on a system
that supports them natively (and Windows does not). It is the same as
any version of JtR starting with 1.7.6 in this respect.
1.7.9-jumbo-6 supports sha512crypt on any system with OpenSSL 0.9.8 or
newer. (Note that it may also be built with OpenSSL 0.9.7, in which
case this functionality is excluded.)
Due to work by JimF, some future jumbo version (although perhaps not the
very next one) will support sha512crypt unconditionally, without a
dependency on OpenSSL version. (We already have this code in git.)
