library test does not build on QNX

[christian.leutloff@…]

The file boost/test/impl/execution_monitor.ipp has some build issues on QNX that are fixed through the attached patch. The small patch does not affect other platforms than QNX (testing for QNXNTO). This issue is present for boost release 1.35.0 and the latest development trunk.

These is the first error:

qcc.compile.c++ bin.v2/libs/test/build/qcc/release/threading-multi/execution_monitor.o
