Thanks.

To summarize the above GCC bug.  They have recognized the difference in empty
struct sizes as a bug, and this is now fixed in GCC 8.  So C, C++, GCC, and
Clang should all pass empty structs in the same way - rather than two different
ways.

How this affects dmd?  I guess you will need to revert whatever workarounds
you've applied in order to support the double behaviour.
