devel/csmith: Update csmith to 2.3.0
This new version contains many changes including:
. Added a CMake-based build system (as well as Autoconf-based system).
. Improved ability to generate C++-compatible code:
First, the command-line option --lang-cpp now sets other options automatically (--match-exact-qualifiers, --no-vol-struct-union-fields, and --no-const-struct-union-fields). Second, the new command-line option --cpp11 tells Csmith to generate C++11-compatible code. The default is to generate C++03-compatible code.
. Added command-line options:
--global-variables / --no-global-variables: allow or disallow global
variables (allowed by default)
--const-struct-union-fields / --no-const-struct-union-fields: allow or
disallow const fields in structs and unions (allowed by default)
--strict-float to disallow assignments
between floats and integers. Unless this option is specified, such
assignments are allowed.
--fast-execution that biases Csmith toward
generating faster programs.. Removed --deputy command-line option, which previously caused Csmith to
output annotations for Deputy, a dependent type system for C.
