Thanks, I overlooked this ...

So it's a bug that the C++ parser doesn't handle this correctly?
I'll open a PR if so.

This works for C; the C++ parser appears to go into an
endless loop when given this code ...

Without the outer pair of parentheses, the C compiler says
error: invalid pointer mode 'TI'
I guess this is because of the compatibility issues mentioned
in the last paragraph of the above manual page?
