The only alternative I see is to define a more obscure type
name based on C/C++ and define SIU_PCR_tag as a macro
which expanded to the correct form. If this type has reason
to be used anywhere else, this might be preferred.

But if this is the only place the type is every likely to be used,
I am OK with this.
