I agree...  The Autoconf Archive (ac-archive.sf.net) has a few macros for 
detecting all the different versions of pthreads if you want to try and 
implement this.

Maybe, it won't be anymore portable than jthreads1 since it still uses a
lot of the same *_OFFSET stuff, and it has a lot of code for
JanosVM-specific stuff (resource control, multiple schedulers).  On the
good side, i think it is a bit more robust and has a cleaner structure.
