The gcc info says that long long type is implemented in software if
the hardware cannot handle 64 bit integers. But Intel coprocessors
CAN handle 64 bit integers, and DJGPP still uses slow library routines
to do addition,substraction etc...

Even Turbo Pascal knows of Comp type (64 bit integers) and deals with
it as with ordinary 'Real' numbers. 

Why doesn't gcc use Intel 387 instructions to do 64 bit integer arithmetic?
