For some reason, this line creates the following warning:
directconn.c:67: warning: dereferencing type-punned pointer will break strict-aliasing rules

I don't understand why it only happens for this line, and not the ones
after it. At least this change stops the warning. If anyone knows how to
properly fix it, or whether it's a bug in GCC or something, please let
me know.
