Struct in a union

[Christophe D]

Hello there.

I'm having a difficulties with Struct and Union. I would like to create a struct as a member of a union. Here is my code:

#include <18F452.h>

#include "typedefs.h"
#use delay(clock=10000000)

typedef union
{
int8 _byte;
struct
{
unsigned bit0:1;
unsigned bit1:1;
unsigned bit2:1;
unsigned bit3:1;
unsigned bit4:1;
unsigned bit5:1;
unsigned bit6:1;
unsigned bit7:1;
};
} RESPONSE_1;

typedef union
{
int8 _byte;
struct
{
unsigned bit0:1;
unsigned bit1:1;
unsigned bit2:1;
unsigned bit3:1;
unsigned bit4:1;
unsigned bit5:1;
unsigned bit6:1;
unsigned bit7:1;
};
} RESPONSE_2;

int main(void)
{
RESPONSE_1 response;
response.bit0= 0;

RESPONSE_2 response2;
response2.bit0= 0;
return 1;
}

The compilers says that bit0 is not a member of "reponse" and "response 2". I'm using PCH version 3.170.
I tested my code in Visual studio and the compiler didn't complain.

Am I doind anything wrong?

Thank in advance.

Strange, v3.187 and v3.236 of the compiler give me an error of 'Element is not a member', but version 3.249 compiles without error.
Thing is that I think the older compiler versions are correct and this is an error in v3.249.... maybe it depends on which C standard you are using, K&R or ANSII ?

The way I learned to program this was that you can not have unnamed structs within the union:
