Comment 1 Jerome Lanneluc CLA 2004-12-09 05:57:11 EST 
This was a temporary glitch introduced yesterday.
Fixed TypeBinding#isCastCompiatible(...) to pass in the compilation unit scope
from the binding resolver and reenabled test CompatibilityRuleTests#test013() to
test018().
Comment 2 Frederic Fusier CLA 2004-12-15 07:36:04 EST 
Verified for 3.1 M4 using build I200412142000.
