[sv-bc] Is simple decimal no. allowed in enum declaration

Hi,
Consider the following case:

typedef enum bit signed [2:0] {mon,tues=2, wed, sun=-4} day;

As per LRM, the size of any decimal no. is at least 32. So for '2', 
error is expected. But most of the simulators fail for '-4', but not for 
'2' in the example. Any reason behind that.
