    32  * This test is based on PR27311, where

    33  * formatting 0.0E00 using the format 0.0#####E0

    34  * produced 0.0E--9223372036854775808.  This was down

    35  * to incorrect use of the logarithm function in 

    36  * calculating the exponent.  The log of 0 is negative

    37  * infinity, which explains the bizarre output.
