   2 /* "vms/lev_lex.h" copied into "util/stdio.h" for use in *_lex.c only!
   3  * This is an awful kludge to allow util/*_lex.c made by SunOS's `lex'
   4  * to be compiled as is.  (It isn't needed with `flex' or VMS POSIX
   5  * `lex' and is benign when either of those configurations are used.)
   6  * It works because the actual setup of yyin & yyout is performed in
   7  * src/lev_main.c, where stdin & stdout are still correctly defined.
   8  *
   9  * The troublesome code is
  10  *      #include "stdio.h"
  11  *              ...
  12  *      FILE *yyin = stdin, *yyout = stdout;
  13  * The file scope initializers with non-constant values require this
  14  * hack, and the quotes instead of brackets makes it easy to do.
