So you are arguing that this is a bug in g++.

I don't agree.  To me it seems natural that typeof should simply be
replaced by the resulting type when doing name mangling.  I don't see
why that is any different from the way that a typedef is simply
replaced by the resulting type.  The GNU typeof extension is really
just an anonymous typedef.  I see no reason to treat it differently
for name mangling purposes.

If somebody wants to change g++, then I guess any type defined by
typeof should be replaced by something like
    u LEN typeof_XXX
where LEN is the length of the following string and XXX is the mangled
form of the expression which is the argument to typeof.
