	When I execute Seti@home client (32 Bits executable) on a 64 Bit     
architecture ( HP900A500-A5X i.e ESIEE's A500) ,the expression :      
                                                                      
   "exp(-(0.693 * SQUARE((float)(i) - (float)(ul_TOffset))) /         
(float)(f_SigmaSq))"                                                  
                                                                      
doesn't work with some specific value. For example exp(-89.790901)    
result in an illegal instruction message.                             
                                                                      
I'm using the current xc ( 0307 ) and a quite recent cvs update of the
kernel ( running in a monoprocessor version.
