0.27, 0.28 not described.

Revision 0.26  2007-10-15 04:52:42  ray
Made a change in CLONE_KEY to the way Clone stores refs in the ref hash.
Perl no longer uses the SvANY part of the SV struct in the same way which
meams the old way of storing the hash key is no longer unique.
Thanks to Slaven Rezic for the patch.

Revision 0.25  2007-07-25 03:41:04  ray
Latest patch from Ruslan Zakirov. Patched another memory leak.

Revision 0.24  2007-07-25 03:33:57  ray
Bug fix for 5.9.*, for some reason the 'visible' logic is no longer working.
I #if 'ed it out until I figure out what is going on.
Also removed an old redundant CLONE_STORE, could have been the cause of some
memory leaks.
