I doubt it ever worked with software-emulated 128-bit long doubles :-(
I hate the convoluted logic we use to decide whether to declare the
__make_[sdt]f functions.  I'm checking this obvious patch in for now,
but it would be really nice to clean it up and consolidate the several
duplicate declarations into more logical conditions.  Permission to
proceed?
