    Cygwin: uchar.h: fix definition of uchar16_t and uchar32_t
    Per C++11, uchar16_t and uchar32_t are defined the same as
    uint_least16_t and uint_least32_t.  Also, check for the C++
    version to make sure that the types are not colliding with
    predefined c++ types.
    Fixes: 4f258c55e87f ("Cygwin: Add ISO C11 functions c16rtomb, c32rtomb, mbrtoc16, mbrtoc32.")
