Busybox awk barfing on gcc 4.0.2 build.

So it should be pretty obvious that I got distracted from putting together
busybox 1.0.2 by trying to get a release of my Firmware Linux distro out now
that I got unblocked on that. And I'm using an svn snapshot of the 1.1 line
in this.
So I got gcc 4.0.2 to link things against uClibc 0.9.28, and built yesterday's
busybox snapshot with that, and now I'm trying to _rebuild_ gcc 4.0.2 using
the busybox tools.
And awk is failing to parse gcc-4.0.2/gcc/opt-functions.awk (attached). Try
it with "busybox awk -f opt-functions.awk" and you get
awk: tmp/gcc-4.0.2/gcc/opt-functions.awk:21: Unexpected token
Any clues?
