>Description:
The compiler fails to compile the attached legal code.
The reason for this is that the library has not
implemented uninitialized_fill_n (and presumably
uninitialized_fill) in a conforming manner.

>How-To-Repeat:

>Fix:
The standard defines the semantics in terms of code.
Why not use it?
