[boost] [predef] Using predef-check on 'develop' problem

In a jam file I have for a run test a predef-check which looks like:

run test_variadic_macro.cpp : : : [ predef-check "BOOST_COMP_GNUC >= 
4.3" "BOOST_OS_QNX == 0" : : <cxxflags>-std=c++0x ] ;

When running on QNX with the gcc version greater than 4.3 I would expect 
that -std=c++0x would not be added as a C++ compile parameter to the 
run. Yet it is being added to the run.

Another test confirms that BOOST_OS_QNX is indeed being set to a 
non-zero value.

Is there a bug in predef-check ? Am I using it incorrectly ?
