It is almost certain that there is a compiler switch that you need to turn
on (often -pthread or something like it - consult your compilers
documentation).  Simply defining BOOST_HAS_THREADS without this will get
your code compiling but it is very unlikely to work correctly.

I don't know if this is the issue, but if you search sgi.com for "pthread"
there do seem to be a lot of OS-patches to the pthread lib available.
Probably you need to address this issue on an SGI specific group though to
find out which IRIX versions have a working pthread_mutexattr_settype.
