Oh sorry, the 'unless one wants all interfaces known at front (eg. in 
kdelibs)' was meant as a subordinate in that sentence. I know that that
is not needed with COM (I actually read 'Inside COM' six or more years
ago. The question was, indeed OT and only for the interested, that I 
remembered MS had to add support for it for their C/C++ compiler. Also I
recall Mozilla needs some assembler for XPCom. How this exactly works was
my question.

hasn't changed over time of course.
