Inline C Functions

Any hope of adding the inline keyword to the C51 compiler so that
we can declare functions as inline?

That would be nice, wouldn't it. But no, we can't do that (yet?).

void cntrl_MaskAllInterrupts(void)
{
    EA = 0;
}

This one is very easy.

sbit r_enable_interrupts = 0xAF; // IE.EA,  Enable All unmasked interrupts
void enableInterrupts(void)
{
    r_enable_interrupts = !0;
}
void disableInterrupts(void)
{
    r_enable_interrupts = 0;
}

Take a look at what's in intrins.h in the Keil include directory. Remember, all SFR's in the 8051 are directly accessible in C.
