I have attached the updated acc-tools.jam file located in
boost_1_31_0/tools/build/v1. 

I added the following option to the compile line:

+z - to make the compiler generate PIC (position independent code) --
required for shared libraries.
-w - suppresses warning messages

And to the link line:

-b - to tell the linker to generate a shared library instead of an
executable. I'm assuming that aCC-Link-action is only used for
generating shared library?

Do you happen to know which thread functions where missing?

Hi Jerry,

Thanks for the info.  I don't think we want to define
BOOST_HAS_PTHREADS unconditionally, because IIRC at least some
versions of HPUX's headers don't contain one or two of the functions
used by Boost.Threads

It's more effective to post a patch as an attachment, so there's no
ambiguity about how mailers have mangled it, and so it can be
automatically applied.
