I don't think I said otherwise :-\ But I guess I could have said "QCC
and/or STD library". Basically I don't know when cxxabi.h is or not
available in the QNX setup so it would be up to you to find out and
modify the check in type_id.hpp accordingly.

Perhaps but that's really up to Dave and John who maintain Boost.Python
and Boost.Config respectively.

But by doing that you've prevented the "boost/config/posix_features.hpp"
header from getting included. So you'll need to include it from the
qnx.hpp file so that all the various POSIX checks and settings are correct.

It always uses the boost/cstdint.hpp file. Which in turn include the
cstdint file if present, and attempts to correct any bugs in the cstdint

Ah, more than a month ago now. My change kicks in when the "__QNX__"
macro is defined.

Yea, but I'm not sure why they are defined when usually libstdc++
support wide char io.

For most libraries it should be as easy as:

cd libs/any/test
bjam -sTOOLS=... -sBUILD=... test

Which will run all the tests for that one library. It's also possible to
run one specific test by using the test name instead of "test". First
caveat, some libraries don't have a test directory and the only way to
run the tests in that case is from the status directory. Second caveat,
there are some libraries where the test directories are deeper in their
libs subdirectory.
