I've also observed this on mips-sgi-irix5.3 and mips-sgi-irix6.5, so this
may even be generic (at least not alpha specific).

So we are left with these 2 patches to the C++ front-end:

2005-06-03  Mark Mitchell  <mark@codesourcery.com>

	PR c++/21853
	* typeck.c (casts_away_constness_r): Do not drop cv-qualifiers on
	the pointed-to type for a pointer-to-member.

2005-06-03  Mark Mitchell  <mark@codesourcery.com>

	PR c++/21336
	* cp-tree.h (grok_op_properties): Remove friendp parameter.
	* decl.c (grokfndecl): Adjust call.
	(grok_op_properties): Determine the class of which the function is
	a member by looking at its DECL_CONTEXT, not current_class_type.
	* pt.c (tsubst_decl): Adjust call to grok_op_properties.


Mark, it's not the first time we catch you backporting patches without testing
them on the branch. :-D

And x86-64 if that matters.

You're really too kind.  This was just plain lame on my part.  Thanks.
