The code in question, which deals with the type of the resuling value, appears
to just not know about the ?: operator. The ternary ?: operator is represented
as an ifexp, an op1 and an op2. 

In case of the gcc extension "a ?: b", which is equal to " a ? a : b", op1 is
NULL, which all the regular code knows how to deal with, except the type
dependent stuff for templates.

I tried adding some simple if(op1) tests but I don't think this is the right
direction. Perhaps op1=ifexpr at an early stage would be useful, but this is
beyond my ken.
