[PATCH, libjava] gen-from-JIS nits

[Ralf Wildenhues <Ralf dot Wildenhues at gmx dot de>]

This fixes warnings about implicit declarations of strcmp, exit, enter,
print_table, an extra argument to fprintf, and a missing argc check.
And a typo.

Bootstrapped, regtested i686-pc-linux-gnu.  OK for trunk?

Thanks,
Ralf
