Nicolas Cellier uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-nice.810.mcz
==================== Summary ====================
Name: Kernel-nice.810
Author: nice
Time: 22 September 2013, 1:05:14.525 am
UUID: eb2a7647-cf62-49f2-8436-40b3a52e18af
Ancestors: Kernel-nice.809
Fix log/ln for integers
1) LargeNegativeInteger sends signal:from: which is a pharosim (unimplemented)
2) a negative SmallInteger answers a nan which is not consistent with LargeNegativeInteger nor Fraction
