(svn r26708) -Codechange: replace C preprocessor with all kinds of options to prevent adding certain things to the result and the sed script to remove everything that shouldn't be in the resulting nfo file but came out of the C preprocessor by a small-ish awk program. This means no more breaking if a C preprocessor decides to add more data to the processed file (like GCC's inclusion of stdc-predef.h when not passing -nostdinc). It furthermore more than halfs the time needed for the assemble step of the extra GRF compilation
