Procedure Pointer Components

I'm probably the wrong one, here, too.  At least for trans, I've never 
worked with namespaces so far...

Some comments to your patch from a read-through, although surely not 
everything worth mentioning:

+gfc_symtree*
+gfc_find_ppc (gfc_symbol* derived, gfc_try* t,
+			 const char* name, bool noaccess)
+{

Looks as if indentation got wrong, probably by the mailer though.

+      /* Check for C450.  */

If possible, I'd try to spell this out briefly.  "C450" means nothing to 
me without looking up the standard...

It seems that you do no special trans'ing of PPC calls at the moment but 
rely on the usual trans of c->resolved_sym.  I've not really an idea 
about how this works/should work, but this seems to be the problem of 
your link-time error.  I would expect that this tries to call a symbol 
"ppc" directly, rather than calling via indirection through a 
function-pointer.

I would try to add a new trans method for PPC calls that does this, i.e. 
generate a call to a function-pointer.  But I don't really know if 
there's even something like this...  I just expect it to be like that 
from my expectation that "GIMPLE is nearly C" :D  If that assumption is 
wrong, I've *really* no idea what the problem could be ;)

That's so far everything I came across, probably not much really 
constructive...

Yours,
Daniel
