And the only "standard" way to *get* trigraphs is to use the 'c89' command.
Since ANSI C *can't* specify how to get full conformance, having something
like

	filter_trigraphs file.c | pre_processor | check_syntax | compile

is a perfectly "valid" way to get a conforming compiler.  Unless, as noted
previously, you're on a POSIX-compliant system, in which case you will be
able to use the aforementioned c89 command.
