Android apparently doesn't support implicit conversion so had to do a
cast before the argument is passed.
I added
off_t ot = (off_t) &file->st.st_size;
before _cpp_convert_input, and passed &ot to argument 7 in _cpp_convert_input.
It seems to be working for now (there are other make issues I'm working on)
