No problem. If you end up overriding everything single option from gcc.jam, 
then there's no point in inheriting from gcc.

If you send me the output of test_all.py, I'll take a look.

When I run "bjam -n qcc" on the hello example, I get this:

    qcc.link bin/qcc/debug/main

      QCC  -o "bin/qcc/debug/main" "bin/qcc/debug/main.o" "bin/qcc/debug/a.o"  
      -lm -gstabs+

That is, the "-lm" is there. Is that right? Do you get "-lm" when building 
"hello"? And "libraries"?

Or "-lm" is incorrect and something else should be placed? Or you get problem 
only when running regressions?

In fact, if -lm should always be added, you can hardcode it in the qcc.link 
and qcc.link.dll actions.
