run it through the preprocessor?
Find out how that sourcefile is going to be built (maybe theres a 
makefile with the package? Just run make -n to see how this file is 
going to be compiled). Then take that command line, remove -c and -o 
filename.o, and add a -E. Run that command.
The preprocessed source you will get on the standard output. But beware: 
it will contain all the contents of all included files and of the files 
included by the included files asf. Search for a characteristic code 
sequence of your sourcefile. You should find it at the very end.
