Re: patches to remove K&R vestiges in Bison

| 
|       Remove K&R vestiges.
|       * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
|       * src/complain.c (VA_START): Remove.  Assume prototypes.
|       (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
|       (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
|       fatal): Assume prototypes.
|       * src/complain.h: Assume prototypes.
|       * src/system.h (PARAMS): Remove.
|       Include <limits.h> unconditionally, since it's guaranteeed even
|       for a freestanding C89 compiler.
|       (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
|       * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

Wow, everything is so much cuter this way :)  Maybe we should have
configure die if the compiler is not ANSI.
