unknown b114118ab7 Bug #19342: ...

Several problems here :
 1. The conversion to double of an hex string const item
 was not taking into account the unsigned flag.
 
 2. IN was not behaving in the same was way as comparisons
 when performed over an INT/DATE/DATETIME/TIMESTAMP column
 and a constant. The ordinary comparisons in that case 
 convert the constant to an INTEGER value and do int 
 comparisons. Fixed the IN to do the same.
 
 3. IN is not taking into account the unsigned flag when 
 calculating <expr> IN (<int_const1>, <int_const2>, ...).
 Extended the implementation of IN to store and process
 the unsigned flag for its arguments.
