* decl.c (duplicate_decls): Don't try to unify an implicit typedef
with an explicit one.
(follow_tag_typedef): New.
(lookup_tag): Use it to extract the tag of an explicit typedef.
(xref_tag): Likewise.
patch, testing fix.

>Description:
# g++31 -o pr6465.o pr6465.cc
pr6465.cc:2: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
This is a regression against 3.0.4, which correctly diagnoses the illegal code:
# g++ -o pr6465.o pr6465.cc
pr6465.cc:2: conflicting types for `struct Tk_PostscriptInfo'
pr6465.cc:1: previous declaration as `typedef struct
Tk_PostscriptInfo_*Tk_PostscriptInfo'
Note: This PR replaces PR6465, which can be closed.
>How-To-Repeat:
Compile this code (Also in the attachment)
typedef struct Tk_PostscriptInfo_ *Tk_PostscriptInfo;
typedef struct Tk_PostscriptInfo Tk_PostscriptInfo;
