testing osscon for stable

[PicCoder]

I am just starting to convert a SourceBoost C program to CCS and so have a few questions that are probably elementary to most of you.

My first question has to do with the first lines of code in my SourceBoost program starts:

osccon = 0b01110000; //Setup internal oscillator for 8MHz
while(osccon.2 == 0) ; //Wait for frequency to stabilize

I used the project wizard to create my first project and it generated this line in main:

setup_oscillator(OSC_8MHZ|OSC_INTRC);

but it doesn't wait for the frequency to stabilize. In Help it says that setup_oscillator sometimes returns a value that can be tested for stability and I see that in the PIC16F88 header file there is something called OSSCON_STATE_STABLE. So, on a lark I gave this a try:

while(setup_oscillator(OSC_8MHZ|OSC_INTRC) != OSC_STATE_STABLE);

It compiles with a warning that operator precedence might not be as intended, which I don't really understand.

I also tried this:

while(OSSCON.2 == 0) ;

but got another warning, this time telling me that OSSCON is always false. So, I guess there is a different way of addressing bit 2 of the OSSCON register, right?

So, what is this the right way of doing this very common operation?
