OK, that works very nicely thanks. I really must learn more about bjam. 
It looks extremely powerful. Is the Boost version very different from 
the original? The bjam docs seem a bit sparse, and boost orientated.

You missed the point slightly. The decision should not be made according 
to the compiler (i.e. tools) but against the version of C++ standard 
library, or maybe there should be a "#define BOOST_HAVE_CXXABI_H" 
somewhere which is set in the appropriate 'boost/config/stdlib/*.hpp' 
file? (and detected in the configure script)

Guilty as charged. It picks up on the __QNXNTO__ definition and is 
currently empty, but available for experimentation.

Does it always use the 'boost/cstdint.hpp' file, or does it prefer the 
'cstdint' file if it is present? When did you make the change?

Is there a clue in:

BOOST_NO_STD_WSTREAMBUF                  [no value]
BOOST_NO_STD_WSTRING                     [no value]

???

One further request - in order to break down the problem into smaller 
manageable chinks it would be great to be able to run the tests 
individually. I followed the instructions in the docs but without 
success. Can you confirm the procedure please?
