Fixed bug #32034: On 64bit platforms assigning values of

Browse Source 
storage engine system variables was not validated and
unexpected value was assigned.

value with the probably negative result. That result of
type uint was compared with 0 after casting to signed long
type. On architectures where long type is longer than int
type the result of comparison was unexpected.
