Subject: disable -Wunused-variable when building SWIG-generated OCaml bindings
X-Git-Tag: 2.49.0~62^2~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1cbfadcf870c0a41dbb63984b91bd6c2950f921e;p=graphviz

disable -Wunused-variable when building SWIG-generated OCaml bindings

There is no value to warning about things like this in generated code, which are
just artifacts of how SWIG code generation works. Removes 112 compiler warnings.
