info. This turned out to be rather useful on ia64 for tracking down malloc/free problems. Detect duplicate free()'s - otherwise these show up as a guard1 failure and it looks like corruption instead of something simple like a second free() where there shouldn't be. Deal with libz using libc headers and not seeing the malloc/free stuff that we provide in libstand. Do similar nastiness to what is done for bzlib. Tested on: i386, ia64 (compile, run)
