How to remove lines added by default by the C preprocessor to the top of the output?

Question

I\'m trying to use the C preprocessor on non-C code, and it works fine except for creating lines like this at the top:

# 1 \"test.java\"
# 1         


        

Answer 1

If you're using the gcc preprocessor:

   -P  Inhibit generation of linemarkers in the output from the
       preprocessor.  This might be useful when running the preprocessor
       on something that is not C code, and will be sent to a program
       which might be confused by the linemarkers.

from gcc cpp man page
