  I'm new to Gcc coding, so this answer might be wrong.  If that is the
case,
I expect someone more knowledgeable than me will correct my mistake and
we'll both have learnt something.  Anyway, my first thought on how to deal
with this would be to look up the name of the SYM_REF, find the DECL for
the function, and look at it's return type.

  Was that even close, anybody ?
