How can I find all the variables that are pre-defined in the pre-processor.

Do these come from a configuration file? Or are the compiled in to cpp when

Something like:

        touch test.h; cpp -dM test.h

...will show you all of the predefined macros. These are compiled into the compiler when the toolchain is built.
