State-Changed-Why:
    You can get a list of predefined macros and there expansions with -E -dM, viz:
    
    echo '' | gcc -E -dM
    
    This doesn't list built-ins like __LINE__ or __FILE__ which are variable.  They are documented in the CPP docs at
    
    http://gcc.gnu.org/onlinedocs/gcc-3.2.2/cpp/Predefined-Macros.html#Predefined%20Macros
