Hello Kagamin,
G++ uses C++ abstract class for nsISupports, so its methods calling
convention is C++ as implemented by g++:
http://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/Compatibility.html
Yes, I had a peek at the XULRunner SDK, and it looked something like you say.
Thank you for the link. It looks like the most significant details of the
C++ ABI in this case (for XPCOM to D interfacing) are:
(1) name mangling (which won't be an issue in XPCOM from what I understand)
(2) layout and alignment of virtual tables (*important and effectively handled
by extern(C++) /IF/ the C++ classes meet the criteria specified in the D
spec).
It would be nice if extern(C++) were still ported to D 1.0, but the other
alternative of enabling extern(System) in COM support (instead of extern(Windows)
) will also work. Extern(C++) might turn out to be just another alternative
which would be nice to have.
