I want to echo my thanks as well.  Testing on cygwin with m4.git branch-1.6, 
the coreutils configure script went from:

Autoconf 2.62: 14.984s, 2020328 bytes
Autoconf 2.63.127-b207b: 9.721s, 999215 bytes

giving a >50% reduction in size, and 35% reduction in speed.  The resulting 
configure script is slightly faster, too, although that is harder to measure 
objectively (it takes so long that I end up doing other things in the 
background, so system load varies between timing runs).

And there is still more trimming possible.
