vax vs real_arithmetic

Unfortunately, real.h will not have been included by this time,
so we cannot use
#if HOST_FLOAT_FORMAT != VAX_FLOAT_FORMAT
#define REAL_ARITHMETIC
#endif
I don't see anything wrong with just using software emulation
all the time. I'd be interested in knowing what, if anything,
this does to compile times.
