Whic is not unreasonable as -d is not a valid GCC option.

I suspect so.

For dmd and ldc2 it is a flag relating to deprecated features.

Basically the test looks well ###### in that it is irrelevant for gdc.
I suspect no-one has only gdc installed – everyone uses dmd for
prototyping and then ldc2 or gdc for production – and so the problem
has not arisen till now.

I will take this back to the D compilers folk. Hopefully it will not
take too long. Is there a timebox on getting this fixed?
