Nice/testsuite/compiler/expressions/operators equality-primitive-optional.testsuite,NONE,1.1

Update of /cvsroot/nice/Nice/testsuite/compiler/expressions/operators
In directory 
sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv26705/testsuite/compiler/expressions/operators

Added Files:
        equality-primitive-optional.testsuite 
Log Message:
Correctly compare possibly null values with primitive values by unwrapping
the possibly null value and performing a native comparison. Wrapping the
primitive value and performing reference comparison could return false even
with identical values. (fixes #1090679)
