struct definition problem

Hi,

I'm using KEIL uVision2 V2.20a, This definition doesn't work, anyone know why ?

Usually I'm using this to access each bit separatly in a byte, rather than using shifting ans masking. In my MPLAB C its working fine. But when using this declaration in KEIL I get the error:

ERROR C150 'b0' bit member in struct/union

My struct definition is:

struct structSplitByte
{
bit b0;
bit b1;
bit b2;
bit b3;
bit b4;
bit b5;
bit b6;
bit b7;
};

union unionSplit
{
struct structSplitByte Split;
char cValue;
};



Or does anyone know a better and easy way to access the value of one bit in a byte ?

Thank you,

Aldrin,
