But on Solaris you don't have an "Init task". RTEMS is an embedded
platform, so its behaviour is rather different from other platforms.

It's crucial that omnithread is initialised before anything that uses
it. For your testing, you can comment out the static omni_thread_init in
omnithread.h, but you _must_ create an instance of the init_t class
somewhere (e.g. in main()) before you use anything to do with
omnithread. That's not safe in general, so omnithread can't be changed
for everyone, but it should work for you.

Cheers,

Duncan.
