I ran into a couple of problems getting the latest bison from osu-cis (as
of 17 Mar) running.  I'm compiling with gcc 1.34 on a System V Release 3
machine.  Context diffs are attached below.

First, in reduce.c, fixed_outfiles is declared but unused in
reduce_grammar, and used but undeclared in print_notices.

Second, conflicts.c should use __builtin_alloca if it's available (i.e.
we're compiled with gcc).

Context diffs to fix both:

*** orig/reduce.c	Mon Apr 10 17:01:41 1989
--- reduce.c	Tue Apr 11 11:02:05 1989
***************
*** 112,118 ****
  reduce_grammar ()
  {
    bool reduced;
-   extern int fixed_outfiles;
  
    /* Allocate the global sets used to compute the reduced grammar */
  
--- 112,117 ----

*** 540,545 ****
--- 539,546 ----
  static void 
  print_notices ()
  {
+   extern int fixed_outfiles;

    if (fixed_outfiles && nuseless_productions)
      fprintf(stderr, "%d rules never reduced\n", nuseless_productions);
