PatR f211953b43 WINCHAIN cleanup 
This started out as some formatting cleanup for src/windows.c but
ended up removing calloc() from the WINCHAIN code, plus fixing a
couple of compiler complaints for win/chain/wc_trace.c.

I tried to actually run with +trace enabled and never managed to
get anything to happen.  trace_procs_init() was never called.  I've
never tried to use it before so don't know whether something which
used to work has gotten broken or I'm just doing it wrong.
