I'm out of town, but I managed to build it and compute the current  
time.  It required about 340 MB, top, to compile:

banach-21% time ~/local/tree-ssa/bin/gcc -I../include -I. -Wall -W  
-Wno-unused -O1 -fno-math-errno -fschedule-insns2 -fno-trapping-math  
-fno-strict-aliasing -fomit-frame-pointer -fPIC -fno-common

This is with checking enabled, so I don't think this is an issue  
anymore.

If it becomes an issue, I'll file another report ;-).
