(You probably mean compile time - "run time" usually refers to the  
running of the compiled code.)

The C/C++ preprocessor is just another language the input file is  
being run through, the result being passed to the actual C/C++  
compiler. So you can run any file through the it, if your compiler  
admits it (for example, by turning off the following C/C++  
compilation), write the output to a file, and then pass that file to  
Bison.

Otherwise, Bison does not have that preprocessor built in, though you  
may use preprocessor commands in code that will become embedded in  
the output file that will be compiled by a C/C++ compiler.
