configurator: hide type punning

As for the type punning: gcc-5.1 with optimization (at least) warns about type punning in
the previous example. The new usage should be exactly equivalent to the
old, but just seperates the cast and deref into 2 statements. Frankly,
I'm suprised gcc's type-punning analysis is so limited.
