>Description:
        Compiler warnings in src/exithandle.c.

        There is a certain "dual use" of functions as both
        signal handlers and cleanup functions which inflict
        a function type dilemma.

>How-To-Repeat:
        Compile with warnings taken seriously.

>Fix:

Well, I usually hate casts like the plague but this patch here has
minimal impact on the overall setup and will resolve the trilemma to
get signals_register() cleanup_register(), and atexit() und a hood.
It's a dirty job but someone's got to do it.
