Thanks for forwarding me those. I'm not as confused as I thought I was. ;)

I applied those patches (with some minor changes) for Andrew Cottrell 
(pardon pointing the finger). This was done as part of the type-punning 
fixes for gcc 3.3.x. I didn't realise at the time that the fixes were 
broken, so mea culpa.

Why not just remove the definitions of is*f from <ieefp.h>?

I can revert the patches I applied, once my question about <ieefp.h> 
above is answered.

Thanks, bye, Rich =]
