Thanks for the report.

This platform (Mac OS X 10.5) is quite old [1], and already Mac OS X 10.11
is end-of-life. This test-float failure indicates a problem only with
'long double's, which are hardly used in libunistring (only in the *printf
routines). Therefore I won't spend time investigating it or providing a
workaround (most likely: define LDBL_MAX differently).
