If the headers do nothing, just delete them? If the headers do something, how
can you preprocess the file without the info from the headers?

Please, explain why you think you need to preprocess a file ignoring missing
headers, and you cannot do this simply by removing the headers before
preprocessing.

GCC has too many options, we should be cautious before adding more.
