Severity: minor
Hi folks,
I have a bulk of code which doesn't want to compile with new gcc 3.x.x
The problem is reduced to following example:
-----
$ cat test2.c
struct _struct1 {
int i;
int j;
};
struct _struct2 {
int a;
int b;
};
union _union1 {
struct _struct1 struct1;
struct _struct2 struct2;
};
static union _union1 union_table[] = {
(union _union1)
(struct _struct1)
{
i: 1,
j: 2,
}
};
int main(void)
{
return 0;
}
----
This is not my code, please don't blame me with it!
----
niko@quimpy:tmp$ gcc-2.95 test2.c
niko@quimpy:tmp$ gcc-3.3 test2.c
test2.c:20: error: initializer element is not constant
test2.c:20: error: (near initialization for `union_table[0]')
As you see it compiles without errors with gcc-2.95 but failes with
gcc-3.3
----
Regards,
Andrei

This is not allowed by the C standard, nor is it a documented GNU CC
extension. So gcc 2.95 accepted it only by accident, and this was
fixed later.
