Subject: Improve compatibility detection for <time.h> and <sys/stat.h>: - Move
 <time.h> before other includes on Windows, so we are sure the time_t
 definition being checked doesn't come from <sys/types.h>. - Padding at the
 end of Tcl_StatBuf doesn't influcence binary compatibility, so relax panic
 check accordingly.
