The error message output for templates uses the cached template name (rather
than synthesizing `X<int>' at the message generation time). This of course
means that the canonical template name is used which looks through typedefs.
As it happens I've a rather substantial patch for the error dumping which gives
better control over this kind of thing. The basic problem in error.c is that
all the functions seriously overload the use of the `v' verbose flag to mean
all sorts of different things in different contexts. I replaced this by a bit
mask, separating each switch.
I've not submitted this patch because I need to separate out some other bits
from it and anyway didn't want to add to the backlog I've already got :-) I'll
get round to it when my compute resource is fully functional again :-(
