Fix signed-unsigned comparison.

Browse Source 
Hex literals are interpreted as unsigned, leading to a comparison between
signed max supported function `abcd[0]`  (which was negative) to the unsigned
literal `0x80000006`.  Should not change result since signed is
implicitly converted to unsigned for the comparison, but eliminates the
warning.
