You could look at how things like type_for_mode/type_for_size (sp?) are
implemented. I don't think we can easily go by the names of the types,
since the "same type" will have different names in C, Ada, and Fortran
But, I think we're trying too hard for complex types, right at the
moment. The bit_offset/bit_size thing is right for ordinary floating
point types and we should be able to handle that easily. My guess is
that for complex types we could add DW_AT_GNU_real_type that indicates
which base type is in use.
