Needs to be '%zu' here and several other places in this file for any
parameter which is 'size_t'.

sigaction doesn't exist on Windows so this fails to compile.
I'd suggest processing a constant amount of data, as the other
benchmark programs do, rather than trying to run for a constant
amount of time.
