Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
Configured with: ../gcc-3.1/configure --prefix=/usr
Thread model: single
gcc version 3.1
>Description:
When using g++ frontend, these erroers occure:
test.cpp:4: non-local function `void g1(<anonymous enum>)' uses anonymous type
test.cpp:7: non-local function `void g2(<anonymous enum>)' uses anonymous type

But NOT if using gcc
Commands used are:
g++ -Wall -c test.cpp
gcc -Wall -c test.c
on the same code.
>How-To-Repeat:
// how to declare and use a packed enum ?

typedef enum { v11=1, v12=2 } e1 __attribute__ ((packed));
void g1( e1 par) {}

typedef enum { v21=1, v22=2} e2 __attribute__ ((packed));
void g2( e2 par) {}
