[PD-dev] freeverb's type-punned pointers

[Hans-Christoph Steiner]

Hey,

I want to fix the type-punned pointer problem in freeverb~ so it can  
be compiled with full optimization.  Here's the code snippets in  
question, with the warnings being issued for the FIX_DENORM_NAN_FLOAT 
() lines:

#define IS_DENORM_FLOAT(v)  ((((*(unsigned long*)&(v))&0x7f800000)==0) 
&&((v)!=0.f))
#define FIX_DENORM_NAN_FLOAT(v)    ((v)=IS_DENORM_NAN_FLOAT(v)?0.f:(v))


static inline t_float comb_processR(t_freeverb *x, int filteridx,  
t_float input)
{
	t_float output;
	int bufidx = x->x_combidxR[filteridx];

	output = x->x_bufcombR[filteridx][bufidx];
	FIX_DENORM_NAN_FLOAT(output);

	x->x_filterstoreR[filteridx] = (output*x->x_combdamp2) + (x- 
 >x_filterstoreR[filteridx]*x->x_combdamp1);
	FIX_DENORM_NAN_FLOAT(x->x_filterstoreR[filteridx]);

[snip]


Could I just cast things to (unsigned long)?  Or is there a better way?
