The run-time check isn't explicitly for version 9, but that it matches the value of FMT_MAIN_VERSION at the time the plugin was compiled. There are a couple compile-time checks that initialize the fmt_main structure differently based on a greater-than-8 or 9-or-greater version number.

The code compiles in a single-threaded non-pthread form if HAVE_PTHREADS is not defined.
I'll have to study how other formats use OpenMP to see how much work is involved in replacing the parallel processing support.

Is jumbo officially Linux-only now? I notice the unrar stuff has some GNU C dependencies.
