[Bug c++/14124] New: enum definition with __attribute__((packed)) gives syntax errors

["jcooper at korgrd dot com" <gcc-bugzilla at gcc dot gnu dot org>]

On Linux 2.4.24, using gcc 3.3.2    
   
I'm following the instructions as described here:            
http://gcc.gnu.org/onlinedocs/gcc-3.3.2/gcc/Type-Attributes.html#Type%20Attributes           
           
Specifically, I say           
   enum testEnum { x = 1, y = 2 } __attribute__((packed));           
          
and I get:          
   error: semicolon missing after declaration of `testEnum'          
          
          
I've also tried:         
   enum __attribute__((packed))  testEnum2 { z = 3 };         
   typedef enum { abc = 4 } __attribute__((packed)) testEnum3;         
         
Both which fail with syntax errors.    See cpp and gcc output listings below. 
         
It is not practical for us to use -fshort-enums, so we really need this to         
work.    Please advise!         
         
Thanks
