[PATCH] fix warnings in testreslist.c

[Garrett Rooney]

I noticed a few warnings in testreslist.c in apr-util.  Here's a patch 
to fix them.  Some are similar to the warnings Joe Orton fixed in 
revision 76117, and the other is from calling time when the prototype 
hasn't been pulled in.

Fix two warnings about type punned pointers and strict aliasing on gcc 3.3.4
and pull in time.h if it exists so we can avoid warnings when calling time.
