Attached as test_all_*.txt.bz2. I did a run with each toolset in case 
there are differences.

In this context it is correct.

When I run the regression test from regression.py I get the following 
failure of "math_info" with the commands:

qcc.link 
/hd1/boost-HEAD/results/boost/bin.v2/status/math_info.test/qcc-3.3.5_cpp/debug/math_info

     "QCC"    -o 
"/hd1/boost-HEAD/results/boost/bin.v2/status/math_info.test/qcc-3.3.5_cpp/debug/math_info" 
"/hd1/boost-HEAD/results/boost/bin.v2/status/math_info.test/qcc-3.3.5_cpp/debug/math_info.o" 
    -gstabs+ -V3.3.5,gcc_ntox86_cpp

But then if I cd to lib/config/test and run "bjam --v2 qcc-3.3.5_cpp 
math_info" I get a pass with these commands:

qcc.link 
../../../bin.v2/libs/config/test/math_info.test/qcc-3.3.5_cpp/debug/threading-multi/math_info

     "QCC"    -o 
"../../../bin.v2/libs/config/test/math_info.test/qcc-3.3.5_cpp/debug/threading-multi/math_info" 
"../../../bin.v2/libs/config/test/math_info.test/qcc-3.3.5_cpp/debug/threading-multi/math_info.o" 
   -lm -gstabs+ -V3.3.5,gcc_ntox86_cpp

Ah! I can see now that it has something to do with threading, but then 
all qcc stuff should default to multithreading and there is no switch as 
with gcc. AFAIK qcc always inserts the "-pthread" option automatically 
for gcc.

What's going on here?
