Correct make distcheck and most gcc and sparse warnings.

  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.
