75142d452b Try to make the use of the eoftoken valid. Given that its value 
is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
is used instead of > 0 where appropriate, (ii), depend upon nritems
instead of the 0-sentinel.

Expected to be duplication of nitems, but for the time being...

2c4c30aa95 * src/closure.c (closure): No longer optimize the special case

clearer.

d7913476c4 Use the more standard files xalloc.h' and xmalloc.c' instead of 
Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
difficult and introduced a lot of core dump.  It turns out that
Bison used an implementation of `xmalloc' based on `calloc', and
at various places it does depend upon the initialization to 0.  I
have not tried to isolate the pertinent places, and all the former
calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
someone should address this issue.
* src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
* lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
files.
Adjust dependencies.
* src/warshall.h: New file.
Propagate.
