f/ansify.c uses ANSI features

This problem was noted when I attempted to do a full build
under vax ultrix starting with the native compiler. The file
f/ansify.c contains a number of ANSI features (function declaration
style and stringization of macro tokens). The file is built with
HOST_CC and thus it must be buildable with non-ANSI compilers.
I have enclosed an untested patch for discussion/review.

* ansify.c (die_unless): Provide definition suitable for cpp that
doesn't have ANSI # stringizing operator.
(die, main): Don't use ANSI declaration style.
