Subject: mingle: cast 'name' parameter values in 'agattr' calls

mingle: cast 'name' parameter values in 'agattr' calls

This has no effect at present. However, when moving this code to C++ in an
upcoming commit, it would trigger -Wwrite-strings warnings. This change
pre-emptively prevents these warnings.
