I wrote them a few years back for mozilla and they were part of the port.
Don't know what happened in the meantime, because since alpha support is
removed I stopped spending time into it.
The whole xptcinvoke thing is completely breandead anyway.
The intention was to have a portable interfacing to modules, but in fact
they just read the C++ vtable using assembly, which the compiler can do
without any help.
The assembly calling functions need to know the compiler specific
vtable and not a fixed self defined, which is not what I expected to see.
It took me several days to understand that they want something senseless.
