;; George Bronnikov <goga@rubinstein.mccme.ru> describes options for the
;; PLAN9 native C compiler `8c':
;;
;; -F Enable type-checking of calls to print(2) and other
;;    formatted print routines.
;; -V By default, the compilers are non-standardly lax about
;;    type equality between void* values and other pointers.
;;    This flag requires ANSI C conformance.
;; -w Print warning messages about unused variables etc. (It
;;    does print a lot of them, indeed.)
;; -p Invoke a standard ANSI C preprocessor before compiling
;;    (instead of a rudimentary builtin one used by default).
