Confirmed on the 3.4 branch only, it is already fixed in mainline. If somebody 
could spot the patch that fixed this, we could backport it to the branch.

Mark you fixed this on the mainline with the patch for PR 13975 but for some reason the patch did not 
reach the 3.4 branch or there is some cvs weirdness going on here.

With my snapshots from 20040402, I get for both the 3.4 branch and 
mainline: 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc 
x.cc:4: error: more than one access specifier in base-specified before 
"public" 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc 
x.cc:4: error: more than one access specifier in base-specified before 
"public" 
 
Andrew, which version of the branch did you try? 
 
Gianni: could you try with a newer version of 3.4 (or even the release)? 
 
Thanks 
  Wolfgang

I note that in the release tar ball, the patch is there but not on the branch for some reason.  The two 
versions of the tree.h (where the fix is) are different for the tag for the branch and the release.  The tag 
for the release is newer than the tag for the branch.

Wolfgang, the patch is in the released version, but there is a CVS problem 
going on: if you update the source using the tag "gcc-3_4-branch", the patch 
for PR 13975 (and many others) does not get pulled for some weird reason.

The bug itself is fixed, but I would like to have the CVS fixed as well.

Uh, that is off. How did I get to have a 3.4 CVS snapshot then that 
has the fix? 
 
My CVS checkout certainly contains this patch: 
2004-02-03  Mark Mitchell  <mark@codesourcery.com> 
 
	PR c++/13925 
	* decl.c (start_function): Do not call pushdecl for any 
	instantiation or specialization of a primary template. 
 
	PR c++/14002 
	* semantics.c (finish_id_expression): Do not return an 
	IDENTIFIER_NODE when lookup finds a PARM_DECL. 
 
	PR c++/13978 
	* pt.c (build_non_dependent_expr): Do not build 
	NON_DEPENDENT_EXPRs for FUNCTION_DECLs or TEMPLATE_DECLs. 
 
	PR c++/13968 
	* semantics.c (finish_id_expression): Do not return an 
	IDENTIFIER_NODE when lookup finds a VAR_DECL. 
 
	PR c++/13975 
	* parser.c (cp_parser_simple_declaration): When skipping to the 
	end of the statement swallow the terminating semicolon.

I use contrib/gcc_update and I seem to be getting the right thing. 
 
In any case, I have no clue what is going on over with you, and I 
don't think I can help you here :-(

OK.

I was NOT able to reproduce this problem with 3.4.0.

I'm going to resolve this bug as INVALID - however if there is a CVS problem (as
some have indicated), you're welcome to reopen this (and change the summary) or
open a new bug.

Good job.  My bad (again...)
