Hi Fellow Programmers:

I am getting a compiler warning when I try assign a 1/0 value to a bit (in a structure) based upon a test for the MSB in the right hand side. I am using RIDE-7.14.0001 with RKit-ARM 1.13.0810.

Here is my sample code:

// test file

#define RX_BIT_OVERTEMP 7 // rx bit for over temperature

// from stm32f10x_type.h
typedef unsigned char u8;

// Head Flags Structure
typedef struct
{
u8 no_comm : 1; // no comm bit
u8 jam : 1; // jam bit
u8 hi_temp : 1; // hi temp bit
u8 act_break : 1; // act break bit
u8 comm_lost : 1; // comm lost bit
u8 wire_break : 1; // wire break bit
u8 spare : 2; // spare bits
}head_flags_s;

void test_function(void)
{
head_flags_s s_head_alarm_flags; // temporary variable
u8 head_alarm_flags; // temporary variable
u8 actuator_flags; // temporary variable

// set/clear hi-temp bit according to actuator flags bit 7 (gets a warning):
s_head_alarm_flags.hi_temp = actuator_flags & (1<
