Description Enrico Scholz 2002-04-19 19:42:23 EDT
Description of Problem:

Trying to compile

| struct foo {
|     union __attribute__ ((packed))
|     {
|     };
| };

fails with

| g++3 -c attr.cc
| attr.cc:3: `class' tag used in naming `union foo::<anonymous>'

Compiling with gcc-2.96, s!union!struct! or placing the
'__attribute__((packed))' after the closing brace succeeds. The gcc
documentation states in "Type Attributes"

|    You may also specify attributes between the enum, struct or union
| tag and the name of the type rather than after the closing brace.

so the code should be correctly.
