Subject: ripemd160: Declare variable at the start of its function
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=4822f24f627f452a1282ae6b2764ebf0aee8fa8d

ripemd160: Declare variable at the start of its function

The resulting code is just as clear to read, so lets not require
a C99 compiler to compile this.
