>>In C I can represent the same data multiple ways using structs and
>>unions.  How and can I do this in Ada?
  Sometimes the item that tells which part of the union to use is
actually nearby, and you can just use a straight Ada discriminated
record.  Another possibility is to use a discriminated record where
a case statement on the discriminant tells which of several pointers
to use to point to the actual C data.
