I could not find -e in my version of gcc. Instead -E was there. The man page says

Code:
       -E  Stop after the preprocessing stage; do not run the compiler proper.
           The output is in the form of preprocessed source code, which is sent
           to the standard output.

           Input files which don't require preprocessing are ignored.

gcc -E source.c

will emit the pre-processed source, eg expand headers, macros but do no compilation.
