[Bug c++/16518] New: mutable specifier only applies to first item in declaration list

["jan at etpmod dot phys dot tue dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Consider 't.cpp': 
 
struct foo { 
        void bar() const { m1=1; m2=1;} 
        mutable int m1,m2; 
}; 
 
Compilation (g++ -c t.cpp) gives: 
 
t.cpp: In member function `void foo::bar() const': 
t.cpp:3: error: assignment of data-member `foo::m2' in read-only structure 
 
This shows that the mutable specifier applies only to the first item in the 
declaration list. Is this the correct behaviour? With previous gcc-versions 
both m1 and m2 were considered mutable and this would compile without problems. 
There is no mention of a change in wwwdocs/htdocs/gcc-3.5/changes.html. I am 
not a native Legalese speaker, so 7.1.1(1) wasn't of much help.
