I thought it might be worthwile for us to know quantitatively how much 
"space" and how much "time" we are talking about for this change.

On my machine, at -current as of a few days ago, /usr/obj took 61775 1k 
blocks and took almost 23 minutes to rebuild after /usr/lib/libc.a is
touched.

I then changed the makefile so that *.o files are produced for single 
source file programs, rebuilt the world, touched libc.a again, and then 
built it once more.  In the end, /usr/obj had grown to 62894 1k blocks; 
but the build took only 11 and a half minutes.

So, for about a 1% increase in disk requirements we can have a 100% 
decrease in time.
