I need to define a pre-processor macro (BOOST_USE_SPLIT_STACK) and apply 
a command line option for gcc (<cxxflags>-fsplit_stack) depending for 
gcc version greater/equal to gcc-2.6 in the Jamfile!
How can I do this?

<toolset>gcc,<version> > 2.6: <define>BOOST_USE_SPLIT_STACK 
<toolset>gcc,<version> > 2.6: <cxxflags>-fsplit_stack

?
