Well, they aren't always bigger - some of the smaller programs I've compiled
for my Sun3s and Sun4s are indentical in size. What I find interesting is 
that of the larger programs, the 2 statically linked ones (emacs & epoch)
are 19 & 15 percent larger then the Sun3 version, but the shared library 
programs (mwm & ups) are 35 & 28 percent larger. Anyone have any ideas why?
