I remember reading, under the Turbo C++ help files, that you could turn
off warnings for a certain code block using a certain #pragma option. 
Is this possible under DJGPP?

You see, I've got a code block that, more or less, looks like this:

for(i = 0; i < 256; i++) {
  sine[i] = sin(i*2*3.1415926/256.0)*256;
  cosine[i] = cos(i*2*3.1415926/256.0)*256;
}

In other words, it's calculating the sin/cos values and putting them
into a 24.8 fixed math int.  But, ofcourse, DJGPP complains about
converting a double to an int... but if I typecast to an int with

sine[i] = (int)...

It does calculate the sine/cosine tables right (they all seem to be 0). 
So I'd like to turn off warnings for this little block.  Is it possible?

If not, what's the command line switch to disable this warning globally?

Thanks,
Jeff Weeks
