Search for header files, after all directories specified by

-fpreprocessed
Indicate to the preprocessor that the input file has already been preprocessed. This suppresses
things like macro expansion, trigraph conversion, escaped newline splicing, and processing of
most directives. The preprocessor still recognizes and removes comments, so that you can pass a

Set the distance between tab stops. This helps the preprocessor report correct column numbers in

Set the input character set, used for translation from the character set of the input file to the source

from the locale, the default is UTF-8. This can be overridden by either the locale or this command
