You are correct.  There are times where typedefs are thrown away
(stripped) and only the underlying type is kept.

To my knowledge, this is done when in a template instantiation the
argument is a typedef.  For instance:

template
struct S {
  T p; //#1
};
typedef int tint0;
typedef int tint1;

S s0; //#2
S s1; //#3

At #2, tint0 is stripped (and thus becomes int) when we build the
instantiation S.  So what is built is really S.  Then when
we are to build S at #3, we strip tint1 to get int, and so we
don't build a new S type, we just re-use the one we already have.

So for the instantiation S, when you look at type type of p at
#1, you get int.  Not tint0.

I believe this is done to save resources.  It's more efficient to have
just one S in the system, rather than having S, S
and S.

Unfortunately, there is no easy way around this at the moment.

Otherwise, outside of the context of template arguments, I think we
pretty much keep typedefs around.

Sure, go ahead!  Once the mirror is up and running, please send
us a patch for  http://gcc.gnu.org/mirrors.html  on how you would
like the mirror to be represented there.
