[Bug c++/19190] New: [4.0 regression] warning "value computed is not used" emitted too often

["mueller at kde dot org" <gcc-bugzilla at gcc dot gnu dot org>]

after the fix for #11224 it now emits the warning almost everywhere.. e.g. 
 
=== cut === 
struct breakme 
{ 
    void setAction( unsigned char a ) { act = a; } 
    unsigned int act:8; 
}; 
=== cut === 
 
$ g++ -Wall -c test.cc 
test.cc: In member function ‘void breakme::setAction(unsigned char)’: 
test.cc:3: warning: value computed is not used
