Sorry for not checking, but I guess it could be good for the record (and 
people googling for it) to ask here.. 
The macro for dealing denormals that I have is:

#define undenormalise(sample) if(((*(unsigned int*)&sample)&0x7f800000)==0) 
sample=0.0f

however gcc 3.3 and 3.4 seem to produce an undesired effect
when the optimizer is turned on, rendering this macro unusable..
this breaks freeverb and a few other stuff I have that uses it.

How was/is this fixed properly?

Cheers!
