Here's a version that hides the casting inside generator.  I added a 
template parameter R, the desired return type.  See line 15 where, now, 
the legal cast form works.  static_cast still won't work.

This would ding every use of generator.  Do you create generator.h from 
a higher level form?  I'm an AWK junkie.

      1  #include <altivec.h>
      2
      3  template <unsigned int v0, typename R>
      4  struct generator
      5      {
      6      R
      7      operator() () const
      8          {
      9          union union_type
     10              {
     11              unsigned int val [4];
     12              __vector unsigned int vec;
     13              };
     14          static const union_type un = {v0, v0, v0, v0};
     15          return (R) (un.vec);
     16          }
     17      };
     18
     19  __vector unsigned char zz =
     20      generator <0,__vector unsigned char> () ()
     21      ;
