I use this in HiTech C

typedef struct Port_s
{
    unsigned    bit0    :1;
    unsigned    bit1    :1;
    unsigned    bit2    :1;
    unsigned    bit3    :1;
    unsigned    bit4    :1;
    unsigned    bit5    :1;
    unsigned    bit6    :1;
    unsigned    bit7    :1;
} Port_t;

union
{   unsigned char   Byte;
    Port_t          Bits; }     PortA, PortB, PortC;

and use it like this

if (!PortB.Bits.bit5)
    PortA.Byte = 0xAA;

The compiler understands it and generates good code.
The only difference that I can see is that you have an array of char,
which may be one level of indirection too many. That's just a guess
though.
