How do I specify a simple macro definition, ie. #define SOMEMACRO, in a 
jamfile for the 'compile' rule ? I know how to add a cxxflag, but 
specifying a command-line #define is different fro different compilers. 
Do I have to know the compiler flag for each compiler to do this or is 
their some feature of Boost Build which does it for me ?
