Hi,

I'm going to apply the patch below if there are no objections.

On PowerPC FreeBSD we have DOUBLE = LONGDOUBLE, so w/o the below the
compilation fails with a double 'case' entry.
Something went wrong with the latest upstream patch. And I didn't have a
chance to test earlier.

Ok?

TIA,
Andreas
