Kai, I got your longdouble2 branch merged into my local repo with iOS
support.  I did have to make a few additions to the ldc::longdouble
class, probably due to my build env with different headers (MacOS SDK
bundled with Xcode).  I'll share the updates once the dust settles.

Good news it that longdouble2 works and I get same unittest results as
my exiting kludge to hardcode real to double (6 module unittests fail
due to real value miscompare on my iPad mini).  I think it is time for
me to look closer at the failures: at least one is even documented that
it only works for 80-bit reals.  -- Dan
