Yes, my patch is only a quick fix to enable builds with MinGW again.

Anthony's patch solves the same problem by omitting the code in
comiplations for non-POSIX builds.

My primary goal was fixing the build, so any of these two patches
is fine for me.

A backends/rng-random.c which compiles with MinGW would be even better,
but maybe that needs a little more time. /dev/random is available with
MinGW, so there is no basic problem doing this.
