opps, I missed that question on my earlier reply. No I have no reason  
to be using those options, except that the g95 manual mentions that  
"[...] typical options are -funroll-loops, -fomit-frame-pointer, - 
malign-double and -msse2".

I thought I'd give it a quick try to see if there was any effect on  
the kernel panics (during "make check").
