That is not completely true.  If you have a program that will fit in 640 K
AND it uses no arrays larger than 64K AND it is heavily floating point
dominated then the Microsoft compiler wins. BUT if you have a big
array, OR you have a program dominated by 32 bit INTEGER arithmetic,
then a real 32 bit compiler will win, even for small programs. I have
shown this with tests using Microsoft and MicroWay compilers.
