yup, still there with sources dated 2003-07-29 00:00 UTC.

host is x86 linux Red Hat 7.2.  You'll note that the host compiler
is 3.2.3 with some local mods.  the only mods in that compiler for x86
hosts is that -fno-strict-alias is hard-wired.  (I ran into too many problems
w/ strict aliasing on RH 6.0 systems, on which i need to compile some
binaries.)

as noted previously, no mods to the gcc (or other tools) that i'm compiling.

(because i'm sure somebody will ask, i'll also try to build the tools 
w/ /usr/bin/gcc.  8-)
