Yikes! - this is my first time around a CVS system in anger, I'll need 
to regroup a little and spend some time looking around before wading in.

I tell you, if I could get the money from the faculty I'd be in like a 
shot! ;)

I was hoping that I could just copy thread_pthread.h from a 2.2b and 
plop it into a 2.1 release and see if that sorts things out.

This revision mentions configuration and other files - so I'll have to 
tread carefully.

Having said all that, many thanks for the help Tim - it would have taken 
ages for me to get there (if at all).

cheers,
