Some compilers already do this.  For example, our compilers (available from
Oregon Software) have a "compatibility" switch which allows compilation of
old-style code, including old-style preprocessing.  In this mode, ANSI
features (including ANSI preprocessing and function prototypes) are still
available, allowing gradual migration of programs from old-style to ANSI C.
