Remaining warnings are due to macros that check address or vectors
on the stack and auto generated yacc code.

  Compiled with default flags and also as:
% make CFLAGS=-DENTRY_TRACKING_ON -DDEBUG_ON -DASSERTIONS_ON
  to ensure the "simplification" of code like:
foo.c:
<hash>define DEBUG_VAR foo_VAR
<hash>include "foo.h"
...
foo.h:
<hash>ifdef DEBUG_VAR_NOT_LOCAL
extern
<hash>endif
int DEBUG_VAR;
...
did not change the author's "intended" logic.
