- Remove uses=compiler:c++11-lang.

- Remove broken for FreeBSD < 10.  Will reinstate if errors result.
- Update pkg-descr according to upstream info.

 This is interval.
 
- The package provides data types for verified computing. The implementation
- of intervals in inf-sup format is based on interval boundaries represented
- by binary64 numbers and is standard conforming to IEEE 1788. 
+ The interval package for real-valued interval arithmetic allows to evaluate
+ functions over subsets of their domain. All results are verified, because
+ interval computations automatically keep track of any errors. These
+ concepts can be used to handle uncertainties, estimate arithmetic errors
+ and produce reliable results. Also it can be applied to computer-assisted
+ proofs, constraint programming, and verified computing. The implementation
+ is based on interval boundaries represented by binary64 numbers and is
+ conforming to IEEE Std 1788-2015, IEEE standard for interval arithmetic.
