[Mono-list] Small typing error in System.Decimal

[Tomas Kukol]

Hi folks.

I found small typing error in mcs/class/corlib/System/Decimal.cs in
Divide function. You should check in the second condition, if d1 is
zero, not d2.

I am sending you diff between new and bad version created by the command:
diff Decimal_good.cs Decimal_bad.cs

605c605
<               if (d1.IsZero ())
---
>               if (d2.IsZero ())

Regards
