--- Comment #10 from Rui Oliveira <ruilvo at ua dot pt> ---
So my options are to create like a placeholder, say
```c
typedef struct __attribute__((__packed__)) // Packed isn't really necessary
here I think?
{
float re, im;
} ph_fcomplex_t
```
To silence the warning and get packing to work, and trust
[complex.numbers.general] for a reinterpret_cast into std::complex<float> I
guess.
