[PATCH 0/4] {master} pacify a few issues

[Theophile Ranquet]

Hi,

Yet another batch of small but needed commits.

Clang used to complain about a useless "yyinput' function in an example.  This
is now fixed.

Perl didn't appreciate the use of potentially undefined variables. Also, I
found that the grammars embedded in the script were vulnerable to known (and
now fixed) bugs, which was problematic when benchmarking with older Bisons.

Theophile Ranquet (4):
  bench: pacify script (invalid uses of undefined variables)
  bench: compatibility for Bison <= 2.7
  c++: better silencing of warnings
  examples: please clang
