Dear All,

Reinhold Bader has been feeding me with PDT bugs, most of which are
now fixed in this commit:

Committed revision 252894.

Please note that it fixes a rather major problem in ASSOCIATE. I will
go through the PRs and see if others are now fixed.

Cheers

    PR fortran/82173
    * decl.c (gfc_get_pdt_instance): Use the component initializer
    expression for the default, rather than the parameter value.
    * resolve.c (resolve_pdt): New function.
    (resolve_symbol): Call it. Remove false error, prohibiting
    deferred type parameters for dummy arguments.

    PR fortran/60483
    * primary.c (gfc_match_varspec): If the type of an associate
    name is unknown and yet there is a match, try resolving the
    target expression and using its type.
